Incremental Upgrades

Hi Yacs guys, I installed 7.10 on my server a couple of months ago....it has been fantastic, even with my lack of tech skills..........

I have been attempting to use the incremental upgrade feature in the control panel.

This is what I have done:

A) Clicked: control panel- upgrade then at Scripts page

A) clicked "update scripts"

then at Stage updated Scripts page

A) clicked "yes, I want to stage files from www.yacs.fr"

then

my screen goes blank and says "done" at the bottom of my Firefox browser.

Then

The screens stays blank, I close my browser, log back in my YACS site and click "control panel" and then "extensions" and I see some changes YACS guys, am I doing this correctly??

I would like to be able to use some of the new features like "page templates" and "YACS chat"..but I dont see them after I try the incremental upgrade.

Thanks and with respect, Steve (nj)
