As Acrobat is crashing on your machine, could you try following troubleshooting steps:
1- Reboot the machine once if you haven't already and check if that helps.
2- If issue still persists, try repairing Acrobat using "Repair installation" option under Help menu ( for Windows OS only), reboot the machine after repair and check.
Does this happen when you launch the application or when opening a pdf?
