I'm thinking there may be another issue, possibly just with my install. Last night I played another repeat round of the first engagement in the campaign as the Germans. I got whupped, but advanced to the second engagement. I have the option to "ignore mission fail" deselected so this should not happen, right? Also, even though I played this campaign engagement before and won handily as the German on the default difficulty level, since the upgrade the battles seem very much more one-sided towards the defending Russian forces at this same difficulty level. It's like I'm attacking with a troop of girl-scouts.
I am considering uninstalling the current game and reinstalling the original download, then performing the downloader upgrade and game upgrade in the correct sequence to see if this corrects these issues. Any thoughts/comments?
