Thank you so much for your reply! I tried the "repair game" and that seems to have solved the problem. Images ok, mouse works.
Afterwards I opened Sims 4 and it showed the message "items removed: one or more items may not be installed on your computer or the E.A. Account that is currently logged in does not own these items. One Build Mode item has been removed." I clicked ok.
Then the following pop-up showed: "Emily her to help! Welcome to Live Mode! Would you like a quick tour of the basic controls? If you choose to do the tutorial, you will receive a special gift!"
How do I know what item is removed and what the consequences are? Thx!
Yes, saving works. No mods downloaded at all.
