I'm using the Winplan-mobile.exe package.
I've switched to a different Windows XP Virtual Machine.
I created a new directory and ran Winplan-mobile.exe from there.
During installation I utilized the Activation Code on my 3.5" disks, creating a new REG.KEY file.
I've just executed my turn in the game and submitted my turn.
As a bit of trivia, I ran an MD5SUM signature on all of the REG.KEY files in the directories for the games I play (including the new one I just generated). The MD5 signature is identical for the REG.KEY files.
I did the same for SCRAM21.OLE to see if there was any difference in my installations. The signatures matched for this file as well.
