Error with Snapshot because of specific plugin files

Right now when I try to create a snapshot I receive this error: "An unknown response returned from Snapshot backup attempt. Aborting. Double check Snapshot settings."

So, I looked at the different discussions on your website about this.



However, I have found specifically what is stopping the export. So, how do I get past this - because I set it up where I export every other table except those that tie in with the plugin (which is stopping the export). This plugin is a membership plugin and might obviously have some data I need.

So, what do I do now?
