Hellfire:
Thanks for your report. The briefing for the American side is quite complex, but the briefing for the Japanese has none of that. This makes me believe that some resource of your computer is getting overloaded by the complex briefing.
I have one idea: you might try deleting some of the large "WAV" sound files that are played during the mission briefing. The first one is named "AttentionMissionForTodayHolla ndiaAB.wav", and you'll find it (along with the others) in the "440430" folder somewhere beneath your AH2 "offmiss" folder. Try deleting that file so the briefing just skips that set of associated resources, and then let me know if it goes any farther before crashing. If so, you might also want to just delete "HollandiaIntroAA.wav" and "Hollandia440430Intro.wav". You'll miss out on the narrative portion of the briefing, but you can hear it anyway in the movie that you can download from the web site (Look for the image that says "Hollandia 30Mar1944 Full Mission Recording".
I hope this helps. I'll try to published the trimmed-down version sometime in the next couple of weeks.
