Does it conflict maybe, with an addon of the same name in your's addon folder?

I'm getting the same error as well when it tries to update your finale map.

Can you point me to the file in question so I can take a look?

I uploaded this as a means to test my finale because we can't upload files that seem to be over 140Mb~.(though i had both parts of my campaign under 200Mb)
After uploading it i needed to make a change so i recompiled the finale and uploaded it again and to see how the auto update process works. It gave me this message.

It seemed like it downloaded it yet it did not update. Doing a little digging I think i found that it was downloaded to my Program Files (x86)\Steam\userdata\10806506\ugc\referenced\541820807412120230\myl4d2addons

But never seemed to get moved into the addons/workshop directory..

Can you give this another shot after the update? We're using a different method to get those files now, so you may see different results.

Ok I tried this again. This time to start "fresh" ; searched my l4d2 folders for all vpk's and deleted any found and also any in the UGC area's; i deleted my item from the workshop and uploaded a new copy.

Let it publish and then subscribe to it. Opened l4d2. It downloaded it and works.

I then wanted to "patch" my item so i uploaded a new copy (different file size and little less content in it).

Uploaded the new version. Fine

Started l4d2 the add-ons progress gfx was rotating so it was seeing new content.

Then nothing. This is in the console again:


An error occurred while attempting to download a file from the UGC server!

And now my add-ons window is blank with no content. Saying no add-ons presently installed. But i can host a game via coop and see my level from this window. It shows my orginial addoninfo.txt content(not what the workshop replaces).

The left4dead2_beta\addons\workshop folder still shows the orginal upload and not the updated copy..

If you delete the old one sitting on your disk, does the new one download properly? As in, without changing anything else, just deleting the file from your workshop directory and restarting the game, does the file then show up properly?

OK yes it does and now shows in the add-ons screen.

When playing the campaign from the "choose an addon campaign" window it still shows my orginal addoninfo.txt content. Don't know if thats intended or not. Thinking it would show workshop description and info..

Can you try one more thing? Can you load the game and uncheck that VPK as being loaded? Then try to update and see if it comes down properly. I'm thinking that the file is actually mounted at the time the game is trying to update it and failing to write it to disk. My guess is that if you uncheck it, you'll see it update properly. If so, I can probably make a quick fix for that one. Thanks for the help!

Will try it now!

Yes that works, it downloaded and installed correctly with it unchecked when starting game. I just then checked the file and was able to play the updated copy without restarting..

Ok thanks, I think I know what's going on then and I'll work on a quick fix!

Hi everyone, the latest update should address the issue you were seeing with updates failing to download to disk. It should also delete old and unused VPKs from your drive when the game starts up. Please let me know if you see files going missing when they shouldn't (this should only occur in the addons/workshop directory, and only delete VPKs and JPGs).

Thanks again for you help!
