In short, issue solved.
I was trying to change scenery in my flightsim, but no joy, message states only Administrators have access, I think oh there must be a problem with my XP software, so I go searching but I cannot find a reference as to who is the administrator on my own computer, now Im thinking Im almost sure I loaded myself as Administrator...? Anyhow turns out this evening I ran all my anti software and a full computer health check, then I get a PM telling me to check out the simple steps of 'Control Panel, User Accounts and low and Bhold there I am listed as the computer Administrator....so my issue lies with the FS2004 simulator message, just goes to show how a newbie can be sent on a wild goose chase...?
