Topic: Problem with playback in Logic and for playback outside of Logic

I own a fire face uc.

When i open up a project in Logic pro 9 and push play I get this message:
Error while trying to synchronize Audio and MIDI.Sample Rate 31998 recognized.
Check conflict between Logic Pro and external device

The sound plays at half speed.

When I try to use the uc as a sound card for playback (spottily, youtube) the sound last half a second and then stops.

I tried resetting all settings via total mix and I haven´t touched the fire face usb settings -app . I´ve checked all connections and everything is where it´s supposed to be - connected firmly.

This happened all of a sudden, how do I fix it??
