@ptaco If you kept the 2 exes before the update you can downgrade and scripthook will work fine. You can use these:https://drive.google.com/open?id=0Bxuvk2wXAXAdZjhURjlVWXdvLVU
As long as you have the steam version they should work fine. Just replace the new one in the gta 5 root folder, Hope this helps
