I think, it might be the problem of the scene editor, since I got wme_crash.txt saying:
---------------------------------------------------------
---------- WME crash report: 16-03-2006, 21:22 ----------
---------------------------------------------------------
SceneEdit.exe caused a EXCEPTION_ACCESS_VIOLATION in module SceneEdit.exe at 001B:0044F431
EAX=00000001 EBX=00000000 ECX=0109F3F8 EDX=00000000 ESI=010943E0

CS=001B DS=0023 SS=0023 ES=0023 FS=003B GS=0000
Stack trace:
(null)
Also when I open the scene editor it doesn't always appear on the Taskbar, moreover if I open a scene, and without changing anything try to close it, the Scene Editor asks whether I want to save changes

.
here is my wme.log just in case:
