Mod failed to publish - Arnold Schwarzenegger Taunt Pack

I’m getting a “Mod failed to publish” message whenever I try and upload a converted DE version of this HD Edition mod:

I thought at first it may be foul language, but I’ve renamed any taunts that may come under scrutiny and I’m still getting the error. It’d be much better if the system told me why it has failed to upload.

Any help would be appreciated.
