First, I would post you issue on the VS forum.
Are your collections gone or are those no albums in the collections?
In the vinyl studio folder there should be a mcf (music collection folder) for each collection. The default is My Albums if I remember correctly. There is one folder for each collection. When you do Open Collections in VS it will show you the folder. Do you see the collection files?
If are are technically pretty good, you can make a copy of the collection file (do not do it on the original!) and then look at that with Notepad. You should see each of your albums and a bunch of other information. Don't worry about the specific data. If the albums are there, the collection files are probably OK.
