Firstly did you get LimeWire Pro for the $18.88 with 6 months of free updates from LimeWire?

If so, you should have received an email with your download link to PRO.

Secondly, your inability to burn or transfer music and blame LimeWire is the same as me blaming you for the gas prices. If you want to burn music it takes more than a BIC lighter. If you have a CD Burner it came with come sort of rudimentary burning program.
If you are having computer problems search the INTERNET for articles on Computer file transfers. I believe the book,"windows for dummies" is very good too.
