Unwanted Expansion pack keeps getting reinstalled after uninstalling

            I so know what that is like. 

                 1) I kept having aliens abduct a family of Sims. Then,they just kidnapped my mini-me(aka-me except in the game)  Cute-right? No-every 15 minutes at times, she would get kidnapped. I swear I even heard her whimper right before the last almost abduction.

                 2)  I had disabled the packs I did not want. I also uninstalled then re-installed the game.   It worked-except, I had to keep rush clicking whenever I tried to repair the game.

                3)  Today-one of my Sims asked another Sim to meet him in Strangerville. This is one of the packs I had disabled.  Later, mini-me's sister was almost abducted.

I think she was, I managed to get them to another world.I feel rather frustrated as well as angry.  I didn't buy the game to keep having a Sim being taken away every single day. I really can't fathom what broke to have it happen every 15 minutes.

               4) Realm of magic or whatever it is also was a pain. It got to be I couldn't use potions or anything that was linked to either world.

                   5)  Does anyone have any idea how to make this stop? If it happens again, I might just not play again and I do love the game.

                6)    I don't use mods. I used to punch in cheat codes like crazy. I don't do that anymore. I use mainly a few codes,like 'modify relationship'  and 'death,toggle'false

.                      Help! This is my second time re-installing.
