Can someone comment on software glitch in TOS desktop preventing me to login into livetrading, where they have hardcoded computer hostname into some java file. Following link describes details of this problem and solution on Mac computer. I have windows 7 with exact same problem. I changed hostname, windows hosts file, disabled firewall, allowed TOS rep to remote login, but problem still remains, I can login into papermoney but not into livetrading.
