I have run into trouble with the prelim SKSE where I am able to copy over the SKE_64loader.exe just once, but then steam flags it as a change in game files (which I have never seen before in any game I've modded) then windows prevents me authorization to copy it over just that EXE file (which has never happened before either.) all the other DLL files and everything else copy over fine. Not looking for tech support because this is all new with the AE just coming out so who knows, maybe the stable SKSE wil fix all of this, but damn I wish I hadn't just gotten back into modding last night before the AE dropped.
