You have gone to huge lengths to help me solve this problem which impressed me and I am willing to donate my Express fee regardless of fixing it.
Follow-up.
Regarding my one in ten thousand plus problem with "Simviation.com".
I have now tried downloading on 3 different computers each using a different system and different virus killers and the only constant between all three is the server "iinet".
I have contacted them and will let you know the results.
Be well all and take care......Alan
