Then post in the Script Dragon thread in the mods forum, not here. For the record, when I chose to not have Steam keep Skyrim up to date, no updates were loaded until I changed this. It is perfectly possible to delay updating until your favorite mods/plugins/script extenders are updated to support it. There's no justifiable reason to blame steam.
The topic of this post has nothing to do with Script Dragon. I am simply asking if it is possible to roll back to a previous version and when for some reason after specifically changing my settings to keep Skyrim from updating and it gets updated it certainly does have to do with Steam. Not to mention when I tried to pause the downloading it wouldn't respond and kept downloading anyway. Now that I think of it I should have just disconnected from the internet, haha. But anyway, I've been playing Bethesda games long enough to know that you generally want to wait to update until you hear about the results.
