Hmmm. If you disabled the mod correctly then it should be able to save right away. Did you go to data files and uncheck the box next to the .esp for that mod? Or are you using the Nexus Mod Manager? If so, it should do all the work for you when you deactivate the mod. If you did disable it correctly but you still cannot save, then there is another problem... :\ To correctly disable it, launch the game via Steam, not the Skryim4gb Loader (if you have it), so that you get the menu with "PLAY, OPTIONS, DATA FILES, TECH SUPPORT, EXIT" and select "DATA FILES." Uncheck the box next to Proudspire.esp and click okay, then "EXIT." Start the game however you normally would and see if you can save. One of the comments on the mod page states that if you turn off all the Autosave settings, then you should be able to enter the house and it will supposedly let you manually save again for approximately 24 in-game hours: If that works as hanli427 describes, you should be able to turn off autosave, enter the house, remove any items you wish to keep from areas added by the mod (the smithy room, the new housecarl room, new chests, weapons rack, weapon mounts, etc. Item in areas that the mod did not change should be ok). Then leave the house and manually save (again this is assuming that what hanli427 said works). Then exit the game, uninstall the mod, reload the previous save, and you should be good. If you cannot get it to work like Hanli427 said, then I'm afraid you will just have to live without those items :(. But at least you'll be able to play the game without having to redo a bunch of quests :)
