"Object reference not set" error on Check-In

[willlin87]

I tried to check in my files and received an "Object reference not set" error. This has not happened prior to today, and I have been using the product for several months. I checked the log file at %Temp%/VaultGUIClient.txt and the entry with the error in question is pasted below. I am not sure how to diagnose or reproduce this error.

I'd suggest deleting the client-side cache, as it may be out of sync with the database. Close any open clients first.
