I would wait until 4.03 is released. This should be within the next week or two. MTU is working hard at getting the problems out of version 4 that a lot of people are seeing as evidenced by the number of posts here in the forums about it.
What are you planning on using it for? Home or Profession? The demo does have the songbook part in it, so you might want to download the 4.02 demo and take a look at it. You might like it and it will save you having to build the songbook twice so to speak as it automatically builds it from exactly what you have imported with an ID that makes it very easy to add to the playlist. If you feel after looking at it that you don't need the song book then get the Lite Duo and save $50.00.
Most people pick one computer to import their CDGs from to keep from accidently creating duplicate BookIDs. Saves a lot of trouble when combining all the songs together, but if you are careful and pay attention to the BookIDs you are using for each computer then you won't have any problems.
When you install Hoster on a computer it must be have an internet connection to register with MTU. The same goes for uninstalling. That way when you uninstall your registration is automatically reset at MTU to allow you to re-install on another computer. So changing computers is not a problem. And in case it comes up no you do not lose your imported song files when you uninstall. They and a few other files are not deleted.
Hope this answers your questions and I know you will enjoy using Hoster. I can't even think of going back to lugging CDs around to do a show anymore.
