Hello can someone help me?
I downloaded the editor for mess around but, when i try to unlock it whit my name and password it give me this message.

Any tip are welcome, se ya boys!

There was an issue with the installer but it was fixed. There is a new full installer now:

If you already have 0.7A or other, you can use just this patch:
