ESO Keybind Help

[meklwein]

Not played the game in a few months I log in and then set up my keybinds (I had to resintall the whole thing) only to find Mouse Button 5 is not being recognised and won't bind. So I am asking the Mod community if they can give me a work around for this? Pretty please as its driving me insane trying to use other keys to use the ability bound. walmartone
