*** Fatal Error: Access Violation at 0X0000000000375A98

Any one can help me resolve this error. It happened when I uncheck a line in report windows in chip planner.

How to contact to Altera? How long do you think they'll fix it? This 's the 4th error I've seen in Quartus II 12.1 SP1, which I have just installed to night. It makes me crazy.
