I've been using FS9 for years with no problems yet today when I switched my pc on and clicked on the FS9 icon I got an error message saying "Please login with administrator priveleges and try again". Never seen this before and I haven't changed anything on my pc. Any ideas on how to get around this ...

I've used this one. Very good time indeed and even let my partner sit in the jump seat which she found interesting. For my hour, we took off from Gatwick, landed at Heathrow then taxied around and took off and landed at Luton. Just fitted the hour nicely.
