Error message clicking on the easy social registration module

Greetings support,

I have activated the easy social registration Jewel in the right column of my homepage. The first time I clicked on it test, displayed correctly. After adding a custom field to the Joomla! User registration, not to ES, I now get an error message saying 'Invalid token. Please try again'. I keep getting this even after deleting the the browser cache and refreshing a bunch of times.

Please help!
