Sims 4 Worlds disappear?

I was going to go play sims for the first time in awhile.   But when I tried to load the game all I got was the three base-game ((Willow Creek, Osasis, springs). Newcrest might have been there. I didn't pay attention. But one of my main towns I need (Windeburg) didn't appear.   I did try to repair it but with one I got "error occurred please try again in a few moments" (CL)  And the other one was "Download failed" (VG).  I did double check if everything was installed (and all of them are installed). I'm in the middle of reinstalling the BG and the packs I do have (Everything but Mashico, First Pets, Niffty Knitting, Paranormal, DU SE, EL, JTB and SV or any of the kits). I hope this works because I want to get back to my SimLit..
