After go through normal mode, the game quitted unexpectedly

Today, on Europe servers, after I killed Baal in normal mode, talk to Tyrael and go through the red portal, the Slayer screen appeared, but after I clicked “OK”, the game was frozen, after about 20 seconds, the game quitted unexpectedly. I guess it’s probably my computer’s problem, I use shared graphic memory with DDR memory. I post here because I want to know is there any influence on my character, whether my character is regular on the servers. If not, whether the scheduled maintain can fix the problem.

Thank you Blizzard for reading. My character is called Liquid-S, she’s very important to me, please give me a reply : ) Thank you very much.
