conflict with enewsletter and wordfence

When we added the wordfence plugin to our multisite, the enewsletter choice in the admin sidebar disappears. As super admin we can add it back, but all the newsletters that were created are missing as well as all the newsletter subscribers. If we add subscribers and newsletters and then deactivate wordfence, the newsletters and subscribers disappear again.
The other thing that happens once wordfence is installed is when trying to save a newsletter you get the dreaded "cheatin uh?" message.
The enewsletter and wordfence are both network activated. Any suggestions on what might fix this problem? I'll put a ticket into wordfence also to get their feedback and follow up regarding that.
