Thanks, all
I was able to download, install and run the game without any problems. I am now moving slowly with the campaign tutorial to see how the game works.
as Ratdeath mentioned above the ASLSK series is quite fun. My neighborhood opponent moved away so I decided to look for a computer game similar to ASLSK to have an opponent. The Combat Mission games were mentioned and seem to be highly rated. Has anyone tried the Mark Walker's Lock 'n' Load boardgame or computer game? I played the Band of Heroes boardgame a few time and I see that Walker also has a conversion of the LnL system into one computer game of Eastern Front WW2 called Heroes of Stalingrad (don't know if it is cool to post other vendor links here, but you can google the title and easily find it). The computer version even has "virtual dice" that have a rolling animation!
