D.Tube does not load.

Dear community,

I joined d.tube with the hope breaking away from the advertisement infected other video sharing sites. I was so excited to become the part of d.tube, however after creating an account even though the website loaded i am not able to watch any videos.

When ever i try to play any video i get an error

This has been the case for more than a week. I googled for a solution but coudnt find anything helpful and i also found that many others as well is having the same problem.

Does any one know how to fix it?

Note: I am not using any firewall. I am running Linux Ubuntu.

TIA.
