The game is not loading my saved parks post the December update (update 2)

It loads to the point where there parks are displayed. Ambient sounds of nature is playing but the park doesn't finished drawing and nothing it moving.

If I click on the park, I get the "RollerCoaster Tycoon World.exe" is not responding screen. I have let it try and load for a hour and still nothing.

Opening an NEW park works fine
