Change location floating button

I use Neat Skype Status Pro (v2) and I just need the floatung button moved to the left and a little lower. I cannot find how to do that. When I look with Firebug I see:

element.style {
opacity: 1;
right: 5px;
top: 250px;

I can modify in firebug exactly the location of my floating button, but where to do that in the code?

In the installation instructions at the wordPress Plugin page it says: “Floating skype status – skype button that floats on the left side of your website, but it can also be set to float anywhere else by editing the style files.” But apparently that is for version 1.

Can anyone tell my where to modify the right/left and the top px?
