EATTEXT Stopped working

EATTEXT now gives an unhandled exception error when I click Finish.  Details of the error are in the attachment.  It worked fine last week.  I am using AutoCAD Mechanical 2013.  Installed SP2, which didn't fix the error.  Ran the repair, and then the reinstall options through Windows control panel, but the error persists.

Any help would be appreciated.

Thanks in advance,

Mitch
