I can't launch Borderlands 2 occasionally

Hi guys, please help me on this.

This is the second times I got this issue, when I click play, it shows a notice:“Cannot find game executable to launch. Closing…” I tried to verify the game but the launcher popup another notice said that I have a IS-MF-01-5-5 error.

How do I fix the error and prevent it from happening again? 'Cause the last time it happened. I have to uninstall the game in order to launch it again :frowning:

Thank you so much for reading my thread.

This should really be asked on the Borderlands 2 support page provided by Gearbox.
