sims 4 error 135:e3734d2a:7e180a62

So everything was working fine yesterday as usual. But this morning....I cannot get into my game due to error message 135e373d2a.7e180a262. All I did this morning, after getting the ok from one of the sims mod creators, I downloaded the XMLInjector and Lot51. I did the use the new button to change them to spellcasters at least to break up the monotony of the vanilla game I set up and yes, put some of my mods in (only major ones) plus some much needed CC. Don't tell me to start over again, move everything to a mods folder and painfully move one at a time, opening up a test game with an awful looking townie. Is there another way? And no, already tried repair and don't want to uninstall and install again.
