Lock & Load X - Still seeing the "Trial Expired" watermark after registering

Hey everybody!

As the subject is saying, i have a problem with lock & load X. Ive registered it with the serial i got and it seems to work, because the license manager accepts the serial.

BUT even after rendering the footage again, i still see the "Trial Expired" watermark and cant get rid of it.
I had the trial version before, now when it expired i purchased the "real" version, sadly its not working for me.
Any help is much appreaciated since im getting closer and closer to a due date...

thanks in advance!
