This is not normal Hoster behavior, so there is something funny about your Windows installation.
As Dale said, you must do the Windows Updates using the CUSTOM button, and download everything.
Once every update is downloaded AND installed (separate functions that automatically happen), if the updates don't require it, I would click the Windows Start button, then "Turn Off Computer..." and then click "Turn Off". Once it is off, wait 5 seconds and turn your computer back on. This will clear out everything that shouldn't be there.
Then run Hoster and click the
Read Manual command to see Hoster's manual. In the Table of Contents, find the topic titled "Importing Hard Drive Files as KMA Files" at the top of the second column. Read this Topic so you know what to do.
The
Import Hard Drive Files screen is incredibly flexible to allow you to import almost any named files. Flexibility comes at the expense of "Ease of Use", so you really MUST read the manual before you try to tackle this screen.
Once you have read the manual topic above, click the Hoster
Import Tracks menu bar, then the
Import hard drive files command and have fun.
If doing all the Windows Updates, restarting the computer, running Hoster again, and clicking the Import Hard Drive Files command still doesn't display the screen, come back here and post what is now happening.
You're doing great in using these Forums and asking for help. Again, this problem is definitely not normal behavior so we are all a bit stumped as to how to guide you. It is very important you follow the given directions here exactly (there are some excellent Technos helping you here). When you describe what you see, please be as specific as you can. When trying to help us re-create your problem, tell us exactly what buttons you click, screens you see (describe them), etc. The more detailed you are, the faster we can succeed in getting your system up and running.
BIG WARNING!!!!!
FYI: Bob Smith, who you paid $70 to, is one of the slimeballs of the Karaoke industry. If I were you, I'd file a chargeback with your bank and get your $70 back. To follow the instructions in his "ebook" will bring you into violation of USA Federal Law (i.e. BIG problems if ever caught), which is grounds for your bank to get you a refund...
PERIOD!
MIRC is an illegal set of servers operating out of Germany. Those who manage the MIRC servers ask no questions. Thus, MIRC has become the stomping grounds of many who are out to download Trojan Horse Viruses on your computer.
When you download a file from MIRC, I guarantee you have no idea who created the files, or what they contain. If you unzip a Trojan horse, its too late. If you do any banking from the same computer, or visit your credit card statement, or investment account, all your Username/Passwords are being sent, probably to a server in Russia (they are notorious for doing Trojans) and before you eat your next meal, they have eaten your accounts. The FBI busted over 4,000 persons on-line who bought data from Russia and instantly made charges around the world. I'm not being insulting here, just giving you the facts. Part of MTU's purpose in business for 39 years is to help educate folks. We are often the first to notify someone of an Identity Theft against them.
Before you download ANY files from MIRC, if you are still of a mind to do so, be sure to install ZoneAlarm on your computer, and do NOT allow any program to send data out. I sometimes scratch my head when I see warnings only to find that in the middle of things, Windows is constantly communicating with Microsoft's servers.
BIG WARNING... if you were to unzip a file and instantly ZoneAlarm showed it is trying to communicate out over the Internet, you've been infected!

I'd click DISALLOW instantly, and unplug my Internet cable connector to take my computer off line until I find the program that has infected it.
Why do I say that? True Karaoke ZIP files NEVER communicate over the Internet. As Dale pointed out, they contain an audio file and a lyrics graphics file that play, not communicate!
You have now received my friendly advice.
