[ACE] Pearl ABS with Materia System: almost works!

Hello!

    I'm using Falcao's Pearl ABS and Victor's Materia System together and I was sure my game would crash but it actually works...almost!  I just need to figure out how to fix two issues:  Materia works perfectly when you equip it. It gives the character its skill that can then be equipped on the skill bar (I did not expect this to work, but what do I know?).  Unfortunately, its skill stays in the skill bar when you unequip the materia even though the character no longer has it.  I'd like the skill to not be usable when the materia is removed from a weapon. The other problem is that AP is no longer given when you defeat an enemy. 

   Are these fix-able? Thanks for any help :)

Here are links to the scripts: Falcao's ABS http://falcaorgss.wordpress.com/2012/12/02/falcao-pearl-abs-liquid-v1/ (the script only comes in a demo as far as I know) and Victor's Materia System http://victorscripts.wordpress.com/rpg-maker-vx-ace/gameplay-scripts/materia-system/

Also, here's a dropbox link to my game file. It's a very rough demo I made just to test the battle systems: https://www.dropbox.com/s/n7mx7m7i6jpl8i9/Untitled.zip
