I'm getting the following error in my usercontrol properties:

Error reading usercontrols/BrandHub/emintRegister.ascx

The following list shows the Public Properties from the Control. By checking the Properties and click the "Save Properties" button at the bottom, umbraco will create the corresponding Macro Elements.

I've tried "/usercontrols/BrandHub/emintRegister.ascx" but I get the same error.

Can anyone help with this?
