Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello! I encountered a strange problem today while I was orchestrating a group for UBRS. Suddenly i got the game-message "Your chat has been disabled for 50000000 minutes".
Just out of the blue. Bam. Tried to relog by nothing happened so now I cant whisp, /s, /g /trade etc. at all.
And for the record , there were no kind of spamming in any kind of chat.
Solutions anyone??
