Schnell Rob

I recently bought CMBB over the internet. Tried to load it on my computer numerous times. Tried cleaning several times. Sometimes loading will terminate midway, usually with a .wav file. Many times will load to final Berlin to Barbarossa.exe file and then get stuck trying to load it. Tried copying .exe file to computer. Computer copies fine ..... until it gets to Berlin to Barbarossa.exe and then won't copy further. What's a poor sap like myself hungering to fight on the steppes to do? Not so schnell Rob
