One thing I noticed in the log:
These are two lines concatenated as the first line seems to be missing part of the path and a newline. I would have said the savegamefolder setting got corrupted, but she did use the tools tab to clear her settings, so maybe this is something else !???
I also notice the logfile does not have EAC enabled anymore while the initial error message was about EAC. Does the server allow connections without EAC? (I may be on a totally wrong track, don't ever use EAC myself)
