Just to clarify, first I use Win 8 Pro, so the new update would be for it not XP, second, I did download 50.2 I have not installed 50.2, third, now we have 50.3. I will download 50.3, but not install it until I know what needs to be done manually installing the download, so it works properly without losing anything. I am ignoring the message for 49.8, I believe, when I load NMM. I run NMM 49.7 currently. I have been going through all of the MODs and updating by uninstalling and reinstalling them individually, so they show current date and MOD versions. My Skyrim is set up as default from the beginning and with NMM. I have not moved anything Skyrim. I wont do the updated until I know my default set up is going to work or could there be problems? I have never moved my Skyrim folder somewhere else, including another independent hard drive.
