skins or one you made yourself (I know mine are pretty poor). If you use RRSkype_friends do you get a custom list showing?
The installer should have checked for .net 2 and registered the plug-in itself. If anything failed it should have told you. However this is one of my first installers so there may be problems. Not sure what you mean by the plug-in is on but not installed.
Anyway I'm here to help you get it running so don't despair yet.
Thanks for your help.
