Exchange 2010 180day trial -> Standard

Been running Exchange in the 180 day trial mode and kept putting off entering the key (lazy). On Saturday I stopped receiving mail, so logged in and opened EMC and it says the 180 day is up.

So ive put in my Exchange 2010 key and activated it OK, but I still am not recieving mail, and sent mail just sits in the drafts folder.. Ive rebooted a couple of times but still nothing...

Any ideas?

Seems the VM ran out of HDD space right about the same time the trial expired. Apparently running out of HDD space causes exchange to stop functioning, with little to no notification I could find.

Screwed up the move of the database to the new hard drive, but Ive recreated it, and populated it from backups, and now exchange is functioning once more.
