Game File Issues

I've recently moved my game to an external hard drive and was initially having issues getting all of my saves and mods/cc to transfer, however it seems I was able to successfully transfer everything but now when I try to load the game on desktop, I get the "TSR_x64.exe not found" message. And when I go on the EA app and try to load it, it stays stuck on "repairing" or "queuing". When I was first trying to transfer onto the hard drive, the EA app created its own version of the game in the Documents folder in my files and none of my data was on the file, it was like a completely new game. I thought I solved the issue when it seemed all of the data successfully transferred but I'm now not even able to open the game. On PC btw.
