Does any version of OPUSFSI run in FSX Service Pack 1 ?
If your going to install SP1 why not install SP2 and get the benefits of both.
Here is the site, look it over and contact them if your only going to load SP1.
I tried RadarMan, but my rig's graphics are apparently not up to par to handle SP2.
Thanks for the prompt response!
Too bad, your next machine will be more than able to do it...good luck!
