Mouse Buttons Not Recognized For Keybinding

[Trokair 1]

I previously had a button on my mouse bound for "Autorun" in the key bindings. Logged in today and it did not work when it did yesterday. Checked my keybindings and it is reset to "X" and does not recognize any of the additional buttons on my mouse. Logged into a different game to confirm the mouse is working correctly and it is there. I have 3 additional buttons on my mouse and none of them work for keybinding. Was something changed or is my client borked?
