Troubll Updating maps on Approach S2

I am attempting to reactivate a Garmin Approach S2 that my deceased golfing buddy left me. I downloaded and installed Garmin Express and it works for my Approach S12. Express recognizes my S2, but no longer supports it. I downloaded Garmin Maps Updater as requested and I keep getting "A connection to the server can not be found. Please ensure that you have internet connection and try again."  I have internet connection, I have cleaned the back of the S2 and purchased a different cable. I have also tried the program on 3 different computers after the firewall has been turned off and I get the same message.

Any other suggestions??
