Hello. I have FSX. after i install the acceleration expansion pack, i No longer have a "Multiplayer" Tab on the left side menu. It is there when Acceleration is not installed, and i can play online also. But when i install acceleration, it just disappears. Also during the acceleration install process, it does NOT ask me for a product key, I have a feeling this has something to do with the problem, Does anyone know how to fix this?
I have Windows Vista 64 bit SP2
