Publisher steam error 8
New, NormalPublic

Description

One specific mod, my main mod will not allow me to update it through publisher anymore. I updated it yesterday with no problem, but today it's error 8; I have tried from different computers as well.

I can even update any of my other mods on the SAME computer just fine, as well as publish the main mod under a different name and it's fine.

I have tried to search and google as much as possible but nothing I found shows any kind of resolution.

Please help
