Try this - Register ITF with the Origin client. Uninstall ITF, then download it through the Origin client. Worked for me with Supernatural. Never needed a disk again. Good luck :D
If you put on the Quantum Power suit, it is permanent. You cannot change outfits! When my Witch exited the Power chamber, her magic was completley depleted!
I just can't see abandoning the Sims 3 after investing so much $$ in the EP's & SP's. I didn't even pay full price. I waited until they came on sale! I will not buy the Sims 4 until it drops below $20.
