It's usually one of two things:
1. Key Maps may be off. Typically you turn them off and turn Repeater (broacasting) on to enter your password during login, but you need to remember to turn Key Maps back on for things like invite and your DPS keys to work, and you want to turn Repeater back off until you need it again (e.g. for accepting/completing a quest). Make sure they're on. You can hit Shift+Alt+M, or click the left icon that ISBoxer adds by default (the one that says A,Z should have a green arrow, the one that says A,A should be grayed)
2. The ISBoxer Addon may be off. Go to the Character Selection screen and make sure it's not disabled.
