What steps will reproduce the problem?
1. Install fubar v3.6.7
2. Install fubar_herbtrackerfu 4.03
3. run game with those addons

What is the expected output? What do you see instead?
I expect to see an icon for the herbtracker somewhere on the fubar, or failing that an option to see the addon via right clicking the fubar. However, I only see an empty fubar-no icons on it to show that herb tracker is even installed.

What version of the product are you using?
latest versions

Do you have an error log of what happened?
yes.
