Can’t open after updgrading to Yosemite

When I upgraded my system to Yosemite, this app failed to launch due to ‘NSInvalidArgumentException’
Here is the error message:
Application Specific Information:
*** Terminating app due to uncaught exception NSInvalidArgumentException, reason: *** -[NSTextView setFont:]: nil NSFont given.
abort() called
terminating with uncaught exception of type NSException

Plz fix this problem
