I paid for the update for Web Designer Premium. I downloaded the latest version and installed it. It removed the old version installed the new one. Unfortunately, when I tried to open my main web page file ( which is 71.0 MB (74,464,748 bytes)  it would seem to load and right when the loading bar at the bottom reached the end , I get a box that says "Web Designer 17 Premium has stopped working." A problem caused the program to stop working correctly and the program closes down.
