Removing any trace of ENB's, including d3d9.dll and EXE's was the first thing I tried. Current ENB version is 0.272. No problem with the ENB outside of MO. The log with only a single session of opening MO, CK and trying to render an outside cell I was working on was over 900K. So unable to attach it. This was with anything relating to any ENB removed. But the last line has the crash, and cause. Good ole c0000005 exception. So, CK is looking for something but is going into a black hole to do it. INFO (23:16:49.0512): Windows Exception (c0000005). Origin: "D:\Program Files (x86)\Steam\SteamApps\common\Skyrim\CreationKit.exe" (57e285). Last hooked call: void *__stdcall CreateFileW_rep(const wchar_t *,unsigned long,unsigned long,struct _SECURITY_ATTRIBUTES *,unsigned long,unsigned long,void *) The crash was reported as: Sig[0].Name=Application Name Sig[0].Value=CreationKit.exe Sig[1].Name=Application Version Sig[1].Value=1.9.36.0 Sig[2].Name=Application Timestamp Sig[2].Value=5522d2ae Sig[3].Name=Fault Module Name Sig[3].Value=CreationKit.exe Sig[4].Name=Fault Module Version Sig[4].Value=1.9.36.0 Sig[5].Name=Fault Module Timestamp Sig[5].Value=5522d2ae Sig[6].Name=Exception Code Sig[6].Value=c0000005 Sig[7].Name=Exception Offset Sig[7].Value=0017e285 Will continue looking from my end, and thanks for the responces thus far.
