Debugging a VP UML Plugin

When I attempt to debug my plugin I get the following error message:

An old version of the project cannot be opened.

But I know it is a current version. Actual error details below:

Hello gcarlson,

Would you mind send me your project file to have a look? You can send it to support-team@visual-paradigm.com. Please include the URL of this post in your email. Thanks!
