Error while reading config file

I've upgraded Log4View to the latest version 12.7.0.862 but am still experiencing the same issue I had with previous versions.

I open Log4View and immediately get an error:
Error while reading config file
Could not load file or asssembly 'DevExpress.Mvvm.v15.2, Version 15.2.12.0, Culture=neutral, PublicKeyToken=BLAH or one of its dependencies.  General Exception (Exception from HRESULT: 0x80131500)

If I check Event Viewer I can see the following:
Application: Log4View.exe

Description: The process was terminated due to an unhandled exception.

Dear Michael,

we are sorry for the inconvenience. We tried to recreate your problem, yet could not trigger this error. Could you send us your Log4View's log file (located at C:\Users\<UserName>\AppData\Roaming\Log4View), so we can narrow down this issue? Our mail address is support@prosa.biz.

In the meantime you can open Log4View by holding down the Ctrl key on startup. This will start Log4View with a fresh configuration.
By the way, are you using any custom plugins?

Yours sincerely
