I use steam on my pc skyrim kept crashing so I deleted skyrim from my library and re downloaded it. after that none of my mods were in my data file so I went through and unsubscribed and resubscribed to them all and they still didn't show up in my data file. but on the loading screen where you can select the data files, at the bottom says that it is synchronizing mods.

I don't know how to fix it!!!!!

PLEASE HELP!!!!!!!!!!!!!

Please post your mod list, and I assume you're unfamiliar with how to post a loadorder. But if you are familiar how to post your loadorder then post it, so people here can take a closer look at it.

My first guess is that you're using mods that requires SKSE, so install http://www.gamesas.com/topic/1568922-wipz-skyrim-script-extender-skse/ (very easy to install) and download the necessary tools for managing your loadorder.

If you have a problem with one of the tools then post your question in the related thread, just to get a faster response than starting a new thread about something you want to know about.

i fixed it!!!!! i deleted steam and redownloaded it!!!!

Glad you manage to fix it by yourself.
