CJB Item Spawner Not working

I recently downloaded CJB Item Spawner, and whenever I press the "i" button it doesnt seem to work, but the cheats button, "p" still works, is there a fixed version anywhere out there?

 

if on the beta the 1.3 the mods beta 3 does not work i tried ((((((((((((

 

I don't know much about how the mods work but I'm on 1.3.23 and beta 3 is working for me, maybe try re-downloading and reinstalling?

 

use beta 2 of the mod
