Psiphon

Hi all, I've been playing the game for some time and all has been well. I've been logging in on a laptop and a PC, the PC is fine but recently I logged onto the laptop and minimised the COH window (run it in a window). Since then when I try to play the game it starts in a minimised view and I'm not able to open the game up. I can hear it and see the window on the taskbar but I'm not able to maximise the window and play the game or change the settings. I've deleted the folder and reinstalled a number of times but the issue remains. I assume that the setting is held on the server. Can you please help? Regards Steve
