Tried to register the third license. Never got a sucess on that machine. I uninstalled the lite version that had expired and installed the latest release. Went to register it again and it said no more licenses left. Went into my account and sure enough it was the third license. Not trying it I deleted that third computer from the account to try again. Now when i try to register it again I keep getting the wrong username or password. I know they are right. I unstalled and reinstalled and still get the wrong username or password every time. Help!
You will probably want to start by resetting your password and see if that helps.
