Whenever i save and close the game, i can't launch it again

One thing you might try if you haven't already, is to use the Save As option.  That sometimes helps with when you have a fail using the Save or Save and Exit options.  Also, you can try using either of the Save options in Live mode rather than elsewhere in the game.  Sometimes, the game doesn't want to save properly at the map or world screens due to some mods that add data to a save file.

Hope this helps.
