I have to disagree with the last post claiming you can not play Combat Arms with Windows 7 operating system. I got the new CA update yesterday and. I am using Windows 7 Ultimate and. I have no problem logging in to CA and playing the game. I am not sure what could be causing other peoples issues but. I can say for a fact it is NOT Windows 7. I do know that if you have no video graphic card in your computer that may cause CA to be slower or not function properly(freeze). I have a GeForce 7600 GT graphic card in my computer. I hope this info has been helpful to all.
Ummm, I've got windows 7 Ultimate 32 Bit edition and it work's fine for me. Have you tried running CA as an admin? If that doesn't work there may be something wrong with your installation, If you would like and it doesn't work reinstall CA and PM me your msn and i can teamview with you to see what I can find?
