Hi, you are welcome,
It might be worth checking the API dashboard for xWeather to make sure that you haven't used all your API calls up. So, go to
xWeather and login using "Account" at the top right. Then click "Login" in the right hand box (API and Mapping), then go to "Usage" from the top menu and you should see something like this:
If "Accesses Allowed" is over 5,000, and % Remaining is negative, you've run out of API calls and need to wait for midnight for it to reset.
Might be worth checking as this has happened to me.
Personally, I would uninstall the old skin and install the new one as this is fully updated and the old one has been without updates for some time now.
