Hi,
we do have a plugin for this website and your links are accepted just fine.
... but:
1. It looks like this is supposed to be video content but it only has a filesize of 126KiB according to their website --> Probably broken content
2. Download does not even work vias website --> Displays error:
Please contact the gounlimited support and ask them to fix it - we are not affiliated with their website and cannot help you with their serverside issues.
