So, what is the point of putting a support ticket in?
I send one in with all the above, clearly stating that I do not have any addons in my community folder, only for them to explain in detail hot to remove any addons, and try the sim again!!
If that fixes the issue, then put the addons back in one at a time.
Oh, and yes, visit the forums for more info.
What a waste of my time and effort
