Invalid Character?

System

I searched for this topic, but wasn't able to get any search results talking about this issue. I was in a team and working on a deep space encounter for the Sirius Sector Patrol. I had a client crash and when I tried to log back in after the file check completed, I was told that my character was invalid to log in. Is this a common problem? Is there a work around for it or is my character corrupted beyond recovery? Any information on this would be greatly appreciated.

Thanks,

***Edit*** Seems I can log in again with my character after taking a bit of a break. Maybe it was just the server coming down that simulated a problem or something similar to this.
