Script Issues with Cheope Theme

I use the Cheope theme and after many support logs with them they have said the issues are all down to woocommerce.

On the checkout you get an error which says username is required but all the fields are full which then stops the customer progressing to pay.

The theme people have said its all java script issues and have included the following links.

Help please
