Each time I start Architect asks for user/pwd - bug?

I move a VM from my laptop to my desktop computer and now each time I star Architect it asks me for user and password.

¿A bug?

¿Or some kind of HW checking for copy protection?

OS: Windows XP SP3

Sencha Architect

version: 3.1.0.1903

channel: 3.1-stable

platform: 1.4.1.960

cmd: 5.0.2.270

Regards.
