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!
