I frequently run a game called ‘Rome Total War’ on my Dell Dimension 3100. It has run alongside Norton Anti-virus 2008 without problem. Two days ago I upgraded to Internet Security 2009 and afterwards the PC refused to recognise that the game disc (original) was in the drive. It kept asking me to insert the correct disc in the drive (there is only one disc). I uninstalled the game and installed it again and still it wouldn’t recognise the disc in the drive (it recognises it ok when installing the game, it’s just when I want to run the game that it gives the error). Uninstalling NIS 2009 has solved the problem, but that leaves me with £44 worth of software that I can’t use, and a PC without any protection. Has anyone any idea as to what the problem is and how to solve it? Thank you.
