I have been using Limewire V4.8.1 Pro for over a year now (successfully). I have tried a search for this but my question is too general and stupid to be asked before. Is 4.12.6 more than 4.8.1? Evidently so. Would I gain anything by upgrading(?) to the newer version? If I do will I need to shell out more $$$$?. As I said it has been more than 6 months since I paid for the Pro version.

Does the downloadable version of the User Manual apply to the new version or to just version 4.9?

I'm getting a lot of wma files in my searches. Is there a way to filter them out so I just get mp3 files when searching music?
Thanks, Musicman
