Osc mac to windows patch migration

Hello, I have an OSC pacth (expressionmap management with cubase) that works very well on a Mac.
I'm trying to install it on a PC and I'm getting error messages that I can't solve.
Nb: I've installed the necessary fx xml-js and xml2js modules.
Obviously a problem with sax...?
Does anyone have any ideas?

It looks like an encoding issue with your xml file (search for how to remove the BOM from a file, could be it).
