Thanks for reaching out to us.
Looking into your account, it appears that you have your camera configured correctly and properly uploading to CameraFTP. In our quick testing, we did not experience any issue with your camera playback. Can you provide us with a bit more detail regarding the issue you are experiencing? Please let us know what browser you are using to try playing this from the web. Please also test to see if you can use the playback feature successfully when logging on from our CameraFTP Viewer application (for iphone, android or windows phone) so that we can verify if this issue is related just with your computer.
Look forward to hearing back from you.
