I have recently formatted my computer and re-installed FS2004, but not FSX.
I have copied my modules-, Gauges- and Aircraft directories over from a backup.
I have re-installed all the reality XP gauges as well as the legendary C-130, C130J and Expansion pack. I have installed FSUIP as well. I have also updated to FS9.1.

Everything works and all aircraft works, but as soon as I load the legendary C-130, Flightsim 2004 shut down after about 8 seconds, without exceptions. If I press S to look at the exterior model I sometimes see a black 8 0 10 sided disk for a prop circle, sometimes it displays normal.

Any ideas? I need to get this running, but maybe I have forgotten something I have done before. It cannot be my system as it worked before the format. I only did not have the expansion set.

System:
2.1GHz Core Duo
2GB DDR2 RAM
512 MB RAM Display (GeForce 7600)
2 X 160GB SATA II HHD
Onboard sound
Win XP SP2

Thank you Tyrion,
Sorry for posting in the wrong section.
I think I found the answer in:
CAPTAIN SIM COMMUNITY FORUM › Legendary C-130 (FS9) › C-130 - General Discussion › Legendary C-130 Extra Pack Support,
if I look at reply 8:
It appears to be the wrong texture format. I will try it at a later stage.
I will convert all the textures of one model to older FS2004 format and see what it does, after I have made a backup of course. To just copy the files over as this guy suggested in reply 8 did not work. But I think I will succeed at a later stage. I will eliminate one thing at a time and later everything except 1 until I find the answer.
Regards
Johan
