Did you go and delete any txc and tmp files like i asked you too?
or at least look to see if there's any there.
I know for a fact your gonna have an eq.tmp file which is generated every time (pretty sure on that)..
if that doesnt help, try deleteing your eqclient.ini, and all *.opt files (do a windows file search and search your EQ dir for *.txc (delete all files), then *.tmp (delete all files), then *.opt (delete all files), then delete eqclient.ini by hand.
