Hi Janrace,
This definitely sounds like an improperly uploaded plugin. Can you download the pro plugin again from this site, then go to your WordPress backend, click on plugins, upload and upload the zip file from there and then activate the plugin.
If you’re still having issues after trying that, can you please email us a set of wp-admin credentials to rob [at] tri.be and reference this thread in the email and we’ll take a look.
Thanks
Joey
