Edge Client Configuration Data Corrupted

We have a similar issue with some users seeing that message (build 7110,2014,807,1842). I checked the client.f5c file that kunjan mentioned above and compared it with a workstation that was working. The affected workstation was missing a bunch of XML data and the attribute was different. So I replaced the client.f5c file on the affected workstation with the file from the working computer and modified the attribute to reflect the correct username. The client seemed to work at first but upon reboot, the problem came back.

I logged into the affected workstation with another user account and the client works normally so it's isolated to a particular user profile. We tried reinstalling the client but it made no change. The client.f5c file still looks good but the message keeps appearing. It's not stopping the client from functioning, but it's annoying for the user.

Any other ideas or config files to check? I couldn't find any other config files in the C:\Users\username\AppData directory pertaining to F5. I saw a bunch on the C:\Program Files(x86) directory but since it's not affecting all users, I don't think it would be a system file.
