The Cobb Tuning AccessPORT Map Manger does not work in Windows 7. I had to setup Virtual Machine XP (XP running in a window). and run the map manager from there. Virtual Machine is only available in Windows 7 Professional or Ultimate. The program runs fine, but it does not find my serial ports. Therefore I cannot connect to the AP. In XP mode it found my serial ports. I am using Win7 x64 Pro.
