steppystep

Thanks for the reply Kelmych! I had backed up several steps with MO but unfortunately the CTD seemed to show up shortly after the core fixes and before the quests were added. That starts to narrow it down to some pretty key pieces of the STEP process unfortunately. I'll play a bit and see if I can pinpoint it. However, with most of my options being CORE pieces, I'm wondering it it may actually be something with my rig outside of the STEP process as it would seem likely that others would have encountered this before.

Reserved for fix attempts/results: 1. Replaced old codec packages with update K-lite package: No change.

Hello all! Desperately seeking help for a consistent and mysterious (to me) ctd. The trouble is upon completing the partial STEP install that as far as I can tell, I've followed instructions on, I have a consistent ctd that seems to be triggered by certain audio, particularly gunfire. I know enough to be able to follow instructions and use the utilities that STEP suggests, but not enough to sleuth my way to a solution! The only other hint I have is that at the time of ctd there remains a consistent repeated sound as if the audio system is hung up on that particular spot.

I stuck with the STEP ini mods. Specifically: the ctd comes when I encounter certain fights, inside buildings, or out in the wasteland. It appears to trigger off of my own weapon firing at times, others, from the NPC's. Any helpful suggestions on where to tackle this would be appreciated. This is about the fourth or fifth time I've attempted to get FO3 modded and stable and I'm about ready to call it in. **edited for format, additional info.
