What steps will reproduce the problem?
1. Install clcInfo & clcInfo_Arms Warrior , have Maque disabled
2. Set it up like described under http://wow.curseforge.com/addons/clcinfo_armswarrior/pages/main/sample-configuration/
3. Enabling Masque having Skins applied will cause a lua error.

What is the expected output? What do you see instead?
i guess Masque is trying to reskin. Options in clcinfo is set to use default and not to use buttonfacade.
On Load a lua error is thrown:
