How to open your map in old version

My map is loading for 1 hour and it is not going to be open please tell me what can I do to edit my map.
Name of the map: europe+
Please fix it or make this html5 editor I paid for Premium and I can't edit my map are you joking?

I'm holding my money until it actually works.

I can't access half of my old maps, Messaged admins about it a long time ago and nothing has come of it so im assuming its broken for good. time to move on.
