Marquee can't read .tmp file

All,

I have a user who can't use the Marquee title tool on one of our Avids.  It keeps giving him the error message: "Can't read .tmp file" and then goes away.  I can't seem to find anything in the knowledge base, do any of you have a clue as to where I would start to solve this?  Other uses can get into Marquee just fine.  It's only him.

Thanks in advance.

George
