Emulator build 4.0-7788 x64 keeps freezing

[Peytop]

Im new to emulations in any shape or form. I thought Id try this one to play games I never had a chance to. Im currently playing Xenoblade, which is the only game I have downloaded so far. I can bring the game up just fine and even play it for a good 5 or 10 minutes. The game runes will run very well, no problems that I can see and then all of the sudden Dolphin just crashes. its happened twice now and I am not really sure why its doing this. Is there anything I can try or would it be the game I downloaded?
