Problem with Notes

Somehow, something got majorly screwed up. I cannot open notes. It opens and immediately shuts. This is the message I get.

Application Specific Information:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Got more than one folder with folderId AAMkAGE0YWY0NWYxLTY5MTktNDQ2OC05ZGU5LWMwZTQyNGQyMzhiMQAuAAAAAACOyHcsYgIDQqIatDkRu5BeAQAVSysgx6srToYHv39HJ0QXAAIQzTxDAAA='
abort() called
terminating with uncaught exception of type NSException


It looks like I had a duplicate copy of Notes in my Burn folder for some reason. I deleted it but that didn't help; still got the above message....what do I do now? I've tried Time Machine; it just says Notes can't be changed because it's a Mac app. I've restarted numerous times as well. Appreciate any suggestions.
