I attempted to play the Sims 3...and when it was finalized stacking; a notice headed up adage that it would be able to not verify if my disc was a valid duplicate and to contact client uphold. This is the same disc I have been playing with following it turned out and the same machine I've constantly utilized and I have never encountered a situation heretofore. I do have a few Mods and stuff introduced, but they have never postured a situation ever, either. It actually doesn't bode well to me. Could any individual serve some useful purpose?
