[cities] fails due to worldweatheronline suspended account key?

I've recently installed the cities scope and although the calculator works fine, weather info is no go... so I decided to do some checking in its files trying to discover what may be wrong in how I was using it (as the expected method of typing a city name just didn't produce anything suggesting that it was even alive).

Finally I located the file /usr/lib/unity-scope-cities/unity-scope-cities and found it had the following URLs:
http://www.worldweatheronline.com/feed/tz.ashx?key=7e70df21c3150016112010&format=json&%s
http://free.worldweatheronline.com/feed/weather.ashx?key=7e70df21c3150016112010&format=json&%s

which when tested (ignoring the query replacement string) both resulted in errors. The first one retrieved the JSON :
{ "data": { "error": [ {"msg": "User account is in suspended mode. Contact support team at <email address hidden>" } ] }}

while the second one is a bit more terminal given that the free.worldweatheronline.com domain doesn't exist! Replacing 'free' for 'www' spits an HTML page saying "Unexpected Error Occured".

My alternatives are:
1) ditch the whole thing
2) register myself in worldweatheronline, generate my own key & patch the files
3) hope that some day the hardcoded key will get unsuspended

I think that option 3 is wishful thinking. 2 is a hassle for something I don't if I want to keep, and 1 is quite tempting...

Suggestions?
