GMPublish PublishWorkshopFile error 2

Dear Community!

I am trying to upload my player models to the Workshop with GMPublish, but I keep getting this error: PublishWorkshopFile failed! (2)
The code:
PublishWorkshopFile failed! (2)
I keep getting this error. I saw the error code list and it says that it’s generic failure.
Whole code:

Garry's Workshop Publisher 1.0
[Compiled Apr 4 2014 - 08:13:14]
Setting breakpad minidump AppID = 4000
Steam_SetMinidumpSteamID: Catching Steam ID: 76561198083136953 [API loaded no]

Sending Addon to Steam..
Sending Icon to Steam..
Publishing "Blackwood Team"
(this can take a long time - it's actually uploading the files right now..)
PublishWorkshopFile failed! (2)

The .gma contains the models, materials and lua codes. No capital letters.
Any help would be appreciated! :slight_smile:

No one helps?
