Allods Online Forum

There were people having the same problem when 4.0 hit, but I forgot the solution. Try the following things:
First, make sure it's the right Allods folder. With the new patch, you might have installed Allods in a different folder.
After that, make sure the folders are named right. It's case sensitive. The folders are data/Mods/Addons.
If that's ok, make sure you have a readme.txt file inside the Addons folder. If you do, open it and make sure it contains this:

If the file doesn't exist, create it and copy->paste the above line in the file.

Too bad the old NA forum is not accesible anymore, there was a good troubleshoot guide there.

I have exactly the same problem. The addons option is not available in the game menu. Have it installed on laptop and everything works fine. After installing latest update to PC the addons problem appeared.
