Hello to all. Granted I am not to good with the PC, but have a few oldies that I get by with. Anyway, I went to the main site..http://www.gameformulatruck.com/en/downloads/ and clicked on parte 1 and everything went along with the normal screens, and then when prompted to click install it asked me to put in Disk 1.?? I could not proceed any further. Any help would be greatly appreciated. Please see attachment.
