vista beta 2 activation unexpected error

When I try to activate Windows Beta 2 64-bit edition, I get a white X in a red circle that says unexpected error. A box can be opened that says An error has occurred Code 0xC002001B Description: The remote procedure call failed. I also am constantly getting screens telling me that the windows licensing service, or something like that, is not working right and asking to report to Microsoft. I don't know if one failure has to do with the other, but if I can't activate soon, it won't matter!

When I tried to submit the above message, I got a prompt that said it had failed. However, when I searched I found it was posted after all. I don't know what is going on here.
