from laptop to desktop

I have recently copied my paks from my lap top to my desktop and the game keeps crashing, Is there anything else that I need to copy to get my laptop game to my desktop,
Thanx

 

there is no log, it just crashes to desktop when I start play, I have a lot of mods, I soppose if I want to continue with my world I need to take them all out and then start putting them back slowly

 

I have followed the steps, my computer seems to be missing the appdata folder, Im still running win8

 

it must be a mod, because I can access the tutorials
