I've updated to latest forge as well, but for me all mods crash, even the updated ones.

I have the same problem. I've tried all v.17.1 versions available (37.0.0, 1 and 2) - all crashes as soon as a mod enters the folder. I've tried several different mods, all up to date with newest version as well.. I've updated Java and every thing I could find related. Really annoying.
