Does SCAL 3 support .GSD files or do I have to convert?
I have a CR collecting dust and I have SCAL 2 but I also have an Expression. I am assuming I would have to buy a second copy, is SCAL 3 available for sale too? I have more than one laptop thank God so I assume I can have one version on one and another version on the other.
Thanks!

Upgrade from version 2 to 3 is free if you previously purchased a license for version 2

I understand this to mean that if you have bought 2 and want 3 also, you may have it free. I don't think it means you have to give up version 2 to have 3..but here is the link if it needs to be purchased...

There might be stipulations as to how many computers can operate at the same time on the same purchased license number, or whatever it is called...

I would type to Craft Edge directly perhaps with the questions.

Thanks!
