can't apply lockscreen

[alessiolecce]

Hi guys! A couple of hours ago i downloaded a lockscreen called Simplicity. I've put it in my mi2a (3.5.3 version) and imported it with theme application, and all went fine. I just can't obtain authorization when i try to apply that. Are you experiencing the same problem? Is it server related?

Edit
i tried also with another lockscreen from same page and i can't apply that too. it's really strange!
