Project Spark

[#1]

Dear Autodesk-Labs

I downloaded Project Spark, and according to the website I use the activationcode as provided.

The software is usable in a previewperiod  and will operate until July 7, 2012.
What are the options thereafter?

Can i still use the files in another version of Spark / Revit LT. What if I use Spark for professional purposes?
Are the created files lost!

Please inform me about the possibilities

Kind regards

Remco Visser

There are 3 options when a technology preview ends.
