I have the same problem, I'm getting the same error message and I have tried with Firefox 3.6.10, Chrome 6.0.472.63 and IE 8.0.6001.18702 (I know three browsers are too much in the same computer :P). I thought it would be related to the change of server but now it's 10/october and I'm still getting the message when I try to establish the draft order, so I can't spend my points. I don't know if anyone is in the same situation. This is the message:
Oops!
Something went wrong with your request. The error has automatically been logged and reported to BuzzerBeater developers. Some errors go away when you hit the back button and try again. If you continue to get an error, you can post about it in the bugs forum.
On the new site, the most common reason for this error is because you were trying to access a page that assumed you were logged in when in fact you were not (probably becuase your session timed out). So simply logging in and trying again might solve your problem. We are working on fixing this more elegantly.
