You could try just bringing up task manager and shutting it down that way.

As for having it not happen again, turn off story progression, move someone in with her, have just her move in with hubby, then enable story progression again.

My problem with installing store stuff is that only some of it gives me a "you must upadate your software... yada yada". My game is fully up to date, version 3.2. I have WA and HELS. Nothing of mine is arred. I tried decrapifying. I tried installing from the dashboard, which told me was installed, but it lied. Since it had lied to me, I tried deleting the contents of the DCCache and then clicking all in the launcher. Again the update software message came up. The items are the renault, hair Curls on the Side, hair Flip, various Around the Sims items and a few patterns I picked up along the way.

Is anyone able to help?
