I'm also using AC in the Cloud and have had this issue.
I find that it happens mainly when I log in from a different computer, though it's not consistent.
The error message is about failing to load Crystal Reports; sometimes it lets me continue with login, sometimes AC crashes before getting to the login screen. In those cases a restart of AC usually works.
I was going to get in touch with tech support about this, but since this seems to be known, I think I'll just wait for now.
