Vasari won't activate

Just downloaded Vasari 3 Beta a couple days ago. But I haven't been able to use the product because it won't activate. It keeps showing a processing error. Please help. Thanks

Thanks so much!

I ended up uninstalling AND deleting the install files (Located at c:Autodesk for me). Then re-downloading the whole thing again and it worked.

Hi, I have found the same problem. I uninstalled Vasari and re-installed the program entering the correct serial number. When the program starts up, it displays exactly the same message as above posted. Please assist, thank you
