I just went in on a Windows 10 pc, Chrome, no additional bits. Worked fine first time I am afraid.
Sometimes your local PC may have something corrupted with a site. If this is the case then try launching a private/incognito window and run it from this. It avoids using the images and files downloaded previously. It does sound like you have used a variety of devices, have you loaded any ad-bashing software to block stuff ?
