Problem to register blindwrite suite 4.3.0.31

I 've had blindwrite suite 4.2.9. I did uninstall it and install blindwrite suite 4.3.0.31. When i register it again with my key from blindwrite suite 4.2.9 it says it’s ok, but when i close blindread or blindwrite and open it again it asks every time to register it. Even after reboot stays the problem the same. Is this a bug?

Did you purchase a key? If so then I would suggest that you contact the BlindWrite team, I am sure they can help you.

I only ask you, as the symptom you mention usually only happens when u enter an illegal key, apologies if this is not the case.

did you copy and paste exactly how it was? remember there are hypens in it as well
