Can't reach server

Hello- I hope you can help me! I just migrated my blogger site to WP and went live yesterday. It was doing ok yesterday but today it's taking about 5 mins to load a page. I was told to do the which timed out repeatedly. I upgraded to PRO and now it's saying "Oh Snap! Seems like Smush Pro server is not reachable, you can try back in some time." HELP??
