I downloaded and installed version 1.5 today.  Seems to be working, however it said my ACE for the 777 was no longer functional, so I deleted it from the taskbar.  Tried to find it under Start, All Programs, Captain Sim, 777, but it is not there, and the icon is gone.  Do I need to reinstall the 777 to get ACE back? Note - the ACE icon for the 737 is still on the taskbar. Also, my F-Secure said I had a virus, which it claims to have removed.  Do I need to turn off my antivirus software, then reinstall the 777?
