Your options include:
1. Using Clean LimeWire, FreeWire or AquaLime
2. Compiling your own version from CVS source
3. Buying the pro version
FreeWire can be downloaded from
http://download.centralserver.net/fr...eWireSetup.exe
Not sure if Clean LimeWire is the same as FreeWire or if it's been dropped. Don't know where AquaLim can be downloaded, but I'm sure MamiyaOtaru can show you.
You need the Java SDK and ant to build from source.
I think LW still needs some things fixed before I'd buy a copy.
