I can't view the film, just opens up with 1 second of duration after I download. May have something to do with my anti-virus, but I can't pause it because I've forgotten the password

I found out about 15 minutes ago exactly how you feel. I was in a ta-152 over our city taking on a set of lancs at 22k. the puffy ack was going off as he was over the target and on my second pass I heard a whack that took off my left gear. I was sure he hadn't fired on me and figured I took a hit from the puffy ack, but I ignored it at the time. For my third pass, I turned into his las buff left as he turned into me and as I passed under him I heard another whack. About 6 seconds later, I was in the tower. I took a look at the film and saw I got set on fire by the friendly ack on the second hit as I passed under him.
I like the new feature if it was intended for puffy ack to be harmful to all aircraft alike, makes it more realistic. Just wish I had known that before I got killed, the ack seemed more trained on my small, agile fighter than the big, lumbering lancs.
