This error only seems to happen to me when I transfer trajectory files between machines. Some kind of flub happens with the FTP or something, and one of my sets gets corrupted. If you used FTP to grab the trajectory from another machine, you should try re-downloading it before rerunning it or something drastic.
I hope your problem is only this simple
