Mahjong Solitaire Epic crashes since update through App Store

I purchased Mahjong Solitaire Epic through the Apple App Store some time ago. Yesterday, I received a pop-up that said there was a new app for my computer in the App Store. Also there was a number on the App Store icon on my dock. Since I never install from a pop-up, I went to the App store and found an update of Mahjong Solitaire Epic waiting. I clicked on it and it installed but it was weird because it installed in less than a minute. After the update, I played this game several times, off and on, throughout the day. I shut the computer down last night. Since starting up today, the game opens when I click on its icon, but then it promptly crashes. I've sent 3 crash reports to Apple, but am wondering if anyone else is having this problem, and how I can go about getting this fixed. Any ideas on who/how to contact the right entity?

Thanks.
