Seems like you either installed a buttload of mods or you had a buttload of mods installed prior to installing UG. Try to get a super clean vanilla San Andreas installation and then reinstall UG. Also next time use the support channel on our discord server for installation/file problems like those.

of course not, I was playing version 4.1.7 and I didn't have that problem, I just updated to 4.2 and I can't start the game
