Ow...I wish I could send mine to you, I presume you're somewhere in europe?
I'm in Canada, and these days, I have a hard time leaving my Pro-one !, I
just got it!

But thanks for the clarifications, I understand now what the mod implies..
Damn I hate being unable to do something by myself!
I don't know anyone in my area (Montreal, Quebec) to help me out.... If
anyone does! let me know!
