I have this really weird thing with Skype. Part of my contact list is gone. 3 people whom I added do not show up in my list. But the weirdest thing is... they're only gone on my own PC. When I log into Skype on another PC, I have my full list available.

There are more differences between using Skype on my and on another PC. On my own, I never show online for my brother. He also can't send me any files. On different PCs I am online and he can send stuff.

I have updated Skype to the latest version, it didn't make a difference. I use Windows Vista.

I'm considering a clean install and see if that helps. Do you have any ideas what it can be?
