Template's and color scheme's location problem

Hi everyone!

I think I got a problem...

First, I can't choose any of the built-in templates and color scheme except the default one (of course on the print screen below you'll see those I created):

 I built a color scheme with the presenter's built-in editor, regularly...

But when I click Ok, nothing happen, I still got the black default color scheme with the name of the new scheme I just created (see image below).

 I tried to figure where exactly it is situated, and instead of the program files folder on my C: disc, it's in my doc and settings/all users/presenter/etc...

So it looks that I cannot access to it. I looked to modify it with the Natalie Timmons' tecnic in this post, but the header is already correct...

Few more details: as we're working on a consolidated internal network, I asked for writing right on my C: disc, to be able to import and use the color scheme, but still not effect...

Did I miss something? I looked inside the playerproperties.xml file to handly put a reference to the color scheme, but I found nothing...
