Our support team can help you but you need to contact us at firstname.lastname@example.org - and when you contact support, please ensure that you give us: ->the account name ->the character name ->your dxdiag file ->as much information about what you encountered as you can, including error messages or screenshots

The more information you give up front, the faster your issue can be resolved.
A DxDiag is a utility designed to display the specifications of your computer hardware, as well as to test DirectX software, including sound and video. If you are asked for this information, it helps the support group relate your gaming issue to your personal computer.
To create a dxdiag.txt just go to Start -> Run (or Search in Vista) and enter dxdiag and click OK. Once the program has run its course, click "Save all Information" and it will output a txt file that you can attach to your email.
I have been getting this too. Usually what I do is back out to the character selection screen and jump back into the game, the download should finish or stop and you should be able to continue playing.
