Events+ plugin slows down my website and doesnt load.

Ok i have just moved my whole website to a new server with no problems really apart from my events+ plugin. Basically anything i load like the calendar, events widgets or shortcodes to display events, just slows down the particular page. It takes ages to load the normal content and then just doesnt load any events. I have reinstalled my whole website multiple times and I am still having the same problem. Any ideas???
