Seems I have a similar problem, I created a second character and, when the process completed, the client crashed. Needless to say since that moment after I login the client CTD no matter what settings I've done or after re-installing the net7 patch.
Could you remove the character Jezmaster under the Jezmiester account? Hopefully that will remove the issue.
P.S. was I wrong to create a second character under the one username?
Cheers
