Well, I have deactivated both firewalls (sw+hw) and set my router to DMZ (Demilitarized Zone) with my local IP adress to let all through.
Guess? Nothing changed... still cannot send any sound.
Is there any way to re-install msgplus completely but keeping the custom away-status, sounds, ... ?
EDIT: (sorry for all those edit's hehe... but that pi**es me off and I tried for about 5 hours now)
I can record my own sounds with microphone and succesfully send 'em to the server, BUT as soon I want to send ANY sound it says "Service unavailable, please try again later" or something similar (german error message).
Only the integrated (with text message) sounds work properly...
Waaaaah!
