Activating a temporary license

Hello,
I requested a temporary license, I received an e-mail.

When I wanted to activate the incoming e-mail with the code below, I received an invalid signature warning.

@ugur.acarr1453,
Hi.
Could you please follow this example and send license to us privately for testing?

@ugur.acarr1453,
I see no issues with this license file on my side. Could you please try this tiny sample project (I have removed license file and library) and test if it works for you?
