Computer crashes with Canadair CL215

I fly with FSX Gold Edition Acceleration. Canadair CL-215 and " Panel fix” of Massimo Taccoli have been installed.
My computer crashes after some minutes of free flight. With the missions Newfoundland SERT or Los Angeles CoFD, I cannot even reach the runway before crash.

Can anybody say if there is a cause and a solution??

Thanks for your help and Happy New Year
