I have just tried to load FM 2010 for the first time I went with using Steam and I can't get FM on at all!!! When I click on the desk top short cut to open it up, it dosen't come up and then when I try again it say it's all ready running. I have look at which programs are installed on the control panel and can't find FM. I tried to uninstall Steam and I can't as it mentions something about other programs are using it - please help me!!!
