Problem with transferring. Please help

I've been trying to transfer my character from Azjol-Nerub to Zuluhed, I've cleared out my mailbox completely, I have no current auctions posted, and I've dropped all of my current quests.

My guild on Zuluhed is expecting me, and I can't make the transfer becase when I go to continue with the transfer, there's an error message saying I have inbound mail, from a quest or something to that extent.

I know for a fact I have no incoming mail, and there are no quests in my quest log...

Please help me. This is extremely frustrating.

Edit: It's been saying this same message since last night. So if I would've had any inbound mail, then it would've arrived by now.
