dcbackup folder

Okay, well, it didn't work, so most likely, I will have to uninstall all the cc...  ☹️  But when I do, do I just uninstall the dccache, or the dccache and the dcbackup, sims, worlds, etc.?

And now...I tried loading my game to see what would happen, & I got the blue circle for a minute, then it said it stopped working & closed out....
