"access violation"

[#1]

I am using jmp 12.01 and experiencing the problem "access violation" just after open a JMP session. The exit button in file menu is grayout and can not be closed by any means except use task manager of Windows.  below are the screen shots. I have emailed to jmp support but would like to check if any member in this forum can help me out.

The issue was fixed finally by choose File/Preference/Windows Specific/ then click on reset association. I guess some file extension was associated with jmp accidentally and caused the issue.
