Spells Left Omni - OK, Not Quite Omnipotent

Perhaps you, the reader, have met my latest creation already ...

I have received my first bit of real feedback - from Europe! Unfortunately, it is bad news.

Apparently the AddOn is doing nothing at all on French computers. I suppose it's a string variable issue ... a likely candidate, right? ... but not being in Europe myself, I'm at a distinct disadvantage. I ask for help.

It is a puzzle! As far as I know, the only 'simple' strings Omni has are:

XML names, like NameOfButton .. "Count"
event names, like "UNIT_MANA"
target names, like "player" / "pet"
playerClass == "DRUID"

The vital piece of the AddOn, mana cost accounting, is string dependent as well, but I am using the localized string MANA_COST, and its other power variants ..

I wouldn't ask anyone to solve this for me, but this is a show-stopper, and I am so far clueless.
