I'm having the same
probelm. Natedog for about 30 hours. I've had to load the client on a friends computer to get the money out. un-install/re-install/deleting all remnants/changing security settings all failing miserably. I cannot even get the program to ever end when I try to get a new version going. UGHHHHHHHHHHHHHHHHHH
Keep me posted if you succeed.
