KML uploaded properly buy not loading anymore

Hello,

I have a Google Maps PRO $ 29 paid plug in working for my website. It started to give error that my licence have expired ( When I purchased I was told its not time plug in and I will get all future free updates ) . Still I paid $19 more to extend it and licence now says my plug in fully functional.

But I am unable to see any KML files that previously worked great. I have four different KML files and none of them show up on map any more.

Here is map link

Please check and fix the KML attachment showing. Its showing uploaded and is in folder but fail to show on map. With KML loading plus will useless for me. I have 10000s of daily website visitors waiting to see the maps on above link so urgent help will be highly appreciated.
