Trie File Open Error.

Earlier this month, my wife started getting the following error while using Outlook 2003:
Trie file open error
Trie File Open Error. C:\PROGRA~1\COMMON~1\MICROS~1\SMARTT~1\Lists\1033\stocks.dat: The system cannot find the file specified.

We had just wiped and reinstalled Windows XP on her laptop, and then went through re-installing all her applications. It seemed that the error went away if we uninstalled AVG Free, and then did a repair on Microsoft Office. But once AVG Free was re-installed, the error came back.

Finally it occurred to me to see if the file really wasn’t in the directory indicated. Nope. Not on her laptop. But I had it on my work laptop. So we copied it to the directory specified in the error message. She hasn’t seen the error message for 2 weeks now.
