CSGO Steam Workshop problem

I'm trying to update on the workshop but it keeps failing for some unknown reason.

Every time I try it seems to upload like normal for a minute or two and then I get the message "Failed to update file! Please try again later". Well it's been like that for almost 24 hours now.

I've tried searching around but it looks like no-one else is having this problem. So is anyone else getting this or had this before?

Also if anyone knows who I could email at Valve about it that would be useful too. Thanks.

edit: I just tried to publish it as a new item and that also failed. "Failed to publish file."

Aha, I did see that and thought it might be related. I'm downloading it now so I'll post again with the results. Thanks a lot.

Unfortunately that didn't help, I'm still getting the error using the CSGO map publisher. Not having any other steam problems as far as I know.

I'm suspicious it broke at the same time they released the new SDK so I'm not sure what's going on.

Well it magically just started working again. I've no idea what I did to fix it.
