Problem migrating to MQ Leaflet plugin from direct tile access

Dear Sirs, we saw yesterday that direct tile access was discontinued! We have now to go back and update all our apps for both iOS and Android versions. This is really amazing. The biggest problem is that we went back and followed the guidelines but nothing worked. We are using Leaflet plugin 0.7.3 and cordova 4.1.1 for iOS. Our code looked like this:

var map = new L.map('map',{

        zoomControl: false,
        attributionControl: false
    });

var ter = new L.tileLayer('http://otile1.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.jpeg',{
            attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
        });

ter.addTo(map);

map.addControl(new L.Control.Layers( { 'Terrain': ter}, {}));

We just changed it to:

var map = new L.map('map',{

        zoomControl: false,
        attributionControl: false
    });

MQ.MapLayer.addTo(map);

map.addControl(new L.Control.Layers( { 'Terrain': ter}, {}));

But the apps gets stucked when we select the map button. We have included in the start html the links to leaflet js css amd map-quest js with are API key set.

Please provide us with a solution asap, since our apps are now off sale.

Thanks in advance,
