Now, after getting all the patches in place i can't play the dam trial

won't let me log on saying that a wow game may not be attached or i may be logging into a region different from one that i created acct in?
Ive emailed support, awaiting reply.
Ive checked their support forum and no help there, ive checked my wtf file for the correct links, all good, funny thing is i can log onto battlenet with my acct details...
i cant post on forums after logging in, it says i don't have a acct linked to it?
This is really frustrating since i waited forever for those friggin patches.
