I have renamed the ListGal.dat file, same problem

Try renaming the entire folder. Again, with Word closed.

I renamed the folder "Word" in the string below. This did not change the problem, but now I seem to have caused another problem. When I click on AppData I get the message "Location is unavailable ... access is denied". Oh dear! I have googled the error, but not sure of what fix to try. Perhaps I should first have clarified which folder exactly I should have renamed, I apologise. I have access to all other files in general, including my Word files.



C:\Users\%Username%\AppData\Roaming\Microsoft\Word \ListGal.dat
