I don't know the answer to your Aces question. Aces Preview doesn't work at all for me, (CTD). OvS doesn't read this forum, so you might ask at his Hell's Angels forum. If you can play the game, I don't think that you have done anything wrong installing Hell's Angels.
The no-moon patch is available from the Hell's Angels site under "Miscellaneous".
PS. I looked around at the HA forum and found that if Aces Preview crashes, you can get in by going first to Pilot Dossiers in Campaigns and looking at your squadron's photos, and then going back to Aces Preview. So I did, and you are right, MvR is not there!
So I asked myself at the HA Forum. I'll post the answer here.
