Impossible to activate my license: "Activation not allowed as remaining quantity is 0"

Hi,

I got an error message while deactivating my license on my laptop, but the deactivation still went through. Now, when I want to activate my license on my main computer, I got the error message: "Activation not allowed as remaining quantity is 0". So now I can't work on either computer.

I tried the offline deactivation, but I get the error message "An error has occurred with your offline-deactivation."

Now I can't work at all. Any idea?
