We just had our computer gone through and XP is my new operating system. I can get the G2 software to install but I can't run it. It just shows the G2 logo that says "LOADING PROGRAM" I can hear the music but no simulator. I installed the newest Direct X from the RealFlight site but still no luck. I also tried to install the latest version of the software but I got a message, something about not being able to connect because something about a firewall. I know nothing about firewalls, and I know very little about computers, I didn't find the RealFlight site helpful for trouble shooting. I hope someone here can help me.
