I have had Tankleader for some time but have not been using it. I downloaded the newest version and entered my key. All is fine, until I try to click "Start" then it locks up. I selected my tanks, left everything as default, but whenever I try to run it it simply lock up, the only way to do anything with it is to End Task (CTR, ALT DEL). I am running WIN 7 64 bit version as that's what I have. Any suggestions?
