[Hustle] Pop up image size on laptops / pc not correct. Mobile lists not working in live

Hi - A couple of issues.
First is a pop up which i want to appear just on laptops and pcs. The image i have on this is not contained within the image block. It was and then one of the support team made changes and now its not sizing properly.
- Second - my slide in for mobiles wont let me enter an email address which is then linked to campaign monitor. It thinks its in test mode when its not.
Please help as this is a really busy time in terms of traffic to site for me so i want to capitalise on this.
