BT Google Maps don't work properly

I installed the module "BT Google Maps" (and others who use the Google Maps service) but does not work in the frontside or the administration side. Do not display the maps, and the administration side buttons do not work for the creation of custom markers. There can be some jQuery conflict problem?

look my site for the problem:
