You can kill this thread or move if you want of course, it is not really an AH2 bug report. More of an XP-64 issue I am sure, beta OS with beta drivers and all are unsupported by HTC of course.
Anyhow, thought I'd post this error and hopefully someone would know what it is. I tried briefly to get AH2 running on XP64 and had no luck. I got a very strange error message:
"Initialization failed with -5 mainSN_FAILED -2"
It was not clear which process or module was reporting this. I went right back to XP32 and flew at 1280X1024X32 with all the sliders on full detail, my frame rates pegged at 82-85 (guess what my refresh rate is ).
