The link to my VR project does not work.

Please log into the VRdirect Studio and make sure that the VR project is currently published. If this is the case, a blue info box on the screen should indicate "Project is published". If this is not the case (and you see a yellow info box), the project is probably only uploaded at the moment but not yet actively published – please press the publish button. 

If such a publication is not possible, please check at the same time whether the account has an active license.
