Computer Crashed,cannot get into Hoster

[Musicmansofie]

Hi, Dont know if anyone can help me but I recently took my computer to a "computer" store to get it looked at, one morning I could only get to my main screen but not into anything, not even my hoster program, they had it for a week and finally said that the only way that they could fix it and this was only hopefully was to copy my files and delete everything from my computer, then put everything back on, I was informed that if I had put software on it myself I would have to contact the company to enable it again, I had some expensive language learning software and I was able to re activate it with help from the company, I have sent an email to MTU support , hopefully they can help, no reply yet. On my main screen I have two folders, one says 'hoster program' and the other just says 'mtu' , when I click on the Hoster program file it comes up with two more files one says 'key text doc.' when that is clicked on there is another window that shows a screen that says on top 'key-notepad' and under in the window shows 2 lines of O's and that is all. Then if I click on the other file which is labeled Hoster 402 setup, I get another window but is black and then disappears right away! Going back to my main screen and to the other file sitting there that says 'mtu' and click on that I once again get two more files, one says'Hoster' and the other 'kma files', the 'kma' file when clicked shows a list of boxes with my song numbers and when the other is clicked'hoster' I get a bunch of boxes each with different names on them - Announcement display, announcement edit, bucket mdb file, def.001.hst,def.002.hst and def.001-4 hst, there are others too but most of them I cannot open because it states that cannot open file needs to know what program created it. I had originally bought version 3.32 and then upgraded to and paid for version 4.02. I must note that I am not a professional karaoke dj, I do a few family parties but mostly use it at home, I have purchased so many extras and probably spent over $3,000, since my 2 sons who are Marines are no longer at home I have only been using it during their visits, my younger coming home from Korea in about a month, they love to use my equipment and I really enjoy joining in the karaoke fun with them, I just can't afford to purchase the software again and hoping that I get some needed help to set it up again, seems I have everything on my computer but then perhaps I am missing a certain file, the computer store cannot help as they know nothing about the Hoster program, can anyone else help? I miss seeing the little desktop shortcut with the picture of the juke box!! I am just miserable! wish I could understand the works of a computer more. I hope someone can understand my dilema
