Mass Effect 1 won't launch due to missing mods

Literally couldn't find anything on the internet so here I am.

So I installed some texture mods, I believe it was "MEUITM" and "A Lot Of Textures". Now obviously like every rational human being I DID backup my game files, but my hdd on which I had the said backup broke. I bought a new one and now when I tried to install Mass Effect 1 from Origin I ran into a problem: When I launch the game it says that some textures are missing and that a bunch of other files are missing. I downloaded the game using the same account onto my laptop and everything worked fine, I was able to use the same save file even (the one that I used mods with). So apparently it's a problem with my PC itself... Please help, I just want to install the vanilla version of the game on my pc!
