If you get an error message and the page doesn't change within 10 seconds, you have to visit this page and download the blaxxun contact software to view/visit the 3d chat worlds.
I have also mirrored the VRML viewing software at this location as a backup to the above original information. Follow instructions on the page.
Having finished the download please close your browser and install the new software. Now should be ready to go into virtual 3D chat by clicking on this link.
