@victoriaengel Origin sometimes tells people to download the Legacy Edition when they don't need it. But to be thorough, please run a dxdiag and attach it to a post:

If you do stay with the Legacy Edition, you may need to replace most or all of your mods and custom content: the LE is essentially still on patch 1.56, and content made for newer patches often doesn't work with the LE.
Sometimes it takes more than one try for the repair to work. Before running another repair though, it's a good idea to clear Origin's cache (and then restart your computer) to force Origin to refresh its data.
