Mods not working after new laptop?

HI everyone! I was an avid sims player for the last few years. I was playing on a mac book, but recently the laptop couldn't handle the size of data needed. So i got a new laptop that runs windows. I put all my mods and everything on a external hard drive. I finally got my sims downloaded on the new lap top but now it doesn't seem to see my old mods. I have tons of mods that I love using and I don't know why its not working. I have already gone through options in the game and enabled script mods. I feel lost on how to solve this. Thank you!
