Hope this can help.
Sampletank 3 needs to be/should already be installed as well. You have to open SampleTank x. and let it rescan the database (each time updated is a good idea). If you have SampleTank3 and you install 4, you still need 3's folder/content because Syntronik uses 3. 3 and 4 and tied together somehow and thats where you have to refresh first, then go back into Syntronic.. I might be late I didn't read all the posts..
