Widget problem

Hi,
First thanks for that awesome plugin.
I′m having some problems with the widget text. Don′t know where to change “Enter email adress…”, delete “Your email” and change “Subscribe” to “ok”.

I read an older question saying something about the .pot file. I only have subscribe2.pot and i found te texts there but if i change them there is no change in the widget.

Thanks!
