Workshop uploader wont upload new addons (2 - Generic Error)

As the title says, I can’t upload any new addons. It just fails once it’s done with "PublishWorkshopFile failed! (2) ". (I looked it up and the 2 just means Generic Error or something like that.)

PublishWorkshopFile failed! (2) 

There’s no “illegal” (non-whitelisted) files, my internet’s not crashing and it’ only 1.9 MB. I’ve googled the crap out of it and no one with my problem has ever gotten a response. I was able to upload addons ~3 days ago.
