Guys..I've been reading all your posts and searching for solution in regard to this d3d9.dll crash. Whenever I placed the enbseries,ini and d3d9.dll in the fsx folder, FSX would crashed. I've tried usereffect=0, changing setting within the .ini with no luck. Until today, I dropped by http://www.gta4-mods.com/misc/icenhancer-12---enb-graphic-mod-f9236 and found out the SOLUTION (and hopefully yours too). I removed OC precision and MSI afterburner (or other GPU fan controller) from my startup and BANG, no move CTD at fsx startup, no more CTD during flight and most wonderful of all, Enb finally works! I know I'm talking about Nvidia card here, but for people with ATI/AMD cards, give this a shot!
