Ok, Ill keep this quick.. I have had hardly any crashes at all with Skyrim and the construction kit, used everyday since launch. I have done absolutely nothing to my computer to cause this new issue I am having, and boy what an issue it is. The Creation Kit now fails to startup giving me an instant crash blah blah message Skyrim has stopped working yada yada....I mean I went to bed last night with everything fine and dandy, so this morning when the CK crashed on startup I thought ok lets try again, and again and again........ Now here I am desperate and gone mad with anger because no matter what I do, be it reinstalling the CK, reinstall the whole of Skyrim, cleaned HD, new graphics drivers and pretty much everything you can do to sort a crash of this kind, it still darn well crashes on start. It dosent even give a reason as to the fault. Its extremely annoying that this manifests itself at the worst possible time for me in the middle of a large mod I have been working on everyday scince launch. I am beyond words. The Ck simply will no longer load. For some reason that is impossible to find or locate it has become totaly 100% unuseable overnight, quite literaly. I could use some pointers as to what I might try that I may have overlooked..! EDIT.. Very strange.. I grabbed a backup Skyrim folder and ran the CK from a different drive letter (E:) and now it loads up again, even the old ones in the original folders.. Hmm. So what the heck did changing the drive letter do to make it work again..?
