Well, I tried that, and the message that came up said that the installation was fine, no errors. I then tried to run the game, and it did start normally, and play fine without crashes. Unfortunately, the next time I went to play, the same problem happened again. I decided to try the installation verification again to see what would happen, and after it completed (and it again said there were no errors), I ran the game and again it worked. So, as a work-around this seems to allow me to at least play, but seeing as it keeps saying there is no error, is there anything I can do for a more long-term fix? I must say it is going to get quite frustrating to need to run the installation verification and wait for it every time I decide to play.
