Raise without a handler error

Running Adobe Acrobat 8.12 Professional. Whenever I attempt to use the text edit tools or the redact tools, I receive an error message stating that "There was a RAISE without a handler. The application will now exit." The only posts I've seen on this issue involve the program 'Pitstop," which is is not on my computer. I've uninstalled, repaired permissions, and re-installed, with no success. It's running on a 15" MacBookPro running Leopard. Thank you.
