Howdy,
yesterday I installed and activated S&M E1 on my notebook. Working fine.
Today I had 1 gig of memory added to the system (it only had 512MB before), and now when I try starting the game it says:
"The security key for this program currently stored on your system does not appear to be valid for this version of the program. Select Yes to enter a new key, or No to revert to the default setting (if any)."
What to do
?
