Is there any difference between the Cloud trial version of SoftChalk Create and the purchased version?

The program is the same; the only difference is that the trial version expires. 

See the below FAQs:

My institution has purchased a SoftChalk Cloud account for me. How do I create a SoftChalk Cloud account and enter my activation key?

How do I enter my license key? My Free Trial desktop version of SoftChalk has expired!
