I come with a problem that occured today not knowing why and how to solve it.
I downloaded the TeamSpeak 3 64-bit version for my 64-bit Windows 7 system some days ago. Today the problem occured that when I close TeamSpeak by clicking the X or doing right-click and close, it is still active as the Task Manager tells me. Also the icon in bottom right corners stays but i cannot hear/talk to people in Teamspeak anymore.
The problem is that it doesn't save the data anymore. E.g. when I want to mute somebody and then close/start again he isn't muted anymore. That happens with all other settings.
The crazy thing for me is that I didn't have the problem the day before.

It would be nice if I could get some solutions for this problem.
