There is a few solutions you can try to fix the issue

1. Switch to steam beta branch (forces steam to update) (dont forget to switch back also test it out what works for you everybody is different)

2. top right screen tap steam"settings", "downloads", change your download server/region (Do not forget to switch back) (switching back atm thou might cause the issue to happen again so test it out)

3. do a full steam refresh without deleting your games (start,Run, (type steam://flushconfig) here is the steam support post for refreshing steam, https://support.steampowered.c…le.php?ref=3134-TIAL-4638

also if a Addon is locked in a state of download at 0/bytes unsub form the mod before you do any of this and make sure to do the steam refresh Last when you have got rid of the stuck download, The stuck download should be your first priority to stop, Without stopping this none of the above will work (well it might but its best to stop it first), And turn off automatic updates while you do so you dont wnat a game updating and messing you up while you are attempting to fix this.

And remember every system is different so what works for one will not work for all.

All information i have posted here you can find on google from 2012-2014 steam forums people had the same issues back then!...

Edit: you can also try this i think TheRingers posted this on another post and it could possibly work also,
Go to steamapps, workshop and then erase the file that says acf 4000 And done. Hope that it works :).
