Have you gone back to check to make sure that the out of date addons are enabled, and ticked (maybe untick and retick to be sure).
Since setting the option, have you logged out your characters and reload your team after setting the load out of date addons? Or even to the char select screen, or even a /console reloadui?


The only reason the standard ISBoxer functions would not work for you are:
1. You have not enabled the out of date addons in WoW
2. You have not performed one of the actions necessary for WoW to reload the addons after you enabled the out of date addons.(methods noted above)
3. WoW has unselected the addon and you have not re-checked it, and then reloaded addons (methods noted above)
4. You are not loading your team with ISBoxer. You should be using one of the 3 methods noted here. Preferably the first one.
5. You have disabled key maps.

JAMBA will work independently of ISBoxer (although ISBoxer sets up a couple of things to work with it too), but you definitely have an issue with the ISBoxer Addon not working, because it is what should be responding to the SHIFT+ALT+I (when you have Key Maps enabled), and it also sets up a few other functions, like ALT+F for follow, ALT+A for assist (assuming you haven't changed the default hotkeys), and also setting the JambaMaster when you switch characters.

Perhaps you should reset your keybinds in WoW to default, Clear your ISBoxer profile (File -> Clear) and re-run the Quick Setup Wizard. If you happen to have a complex ISBoxer Profile, use the File -> Save As menu first.
