The Autodesk Labs site is experiencing technical difficulties. Actually this is a hardware issue affecting all of the Autodesk Community Sites. A team of employees, partners, and vendors are working on the problem. I apologize for the inconvenience. I know many of you want to download the technology previews you learned about at Autodesk University. Thank you for your patience and continued participation in the Autodesk Labs experience.
Troubleshooting is alive in the lab.
UPDATE: The Autodesk Labs site is fully operational again.
