Fabfilter Pro Q3 activation
Could it be that you downloaded Pro-Q 4 and are trying to authorize that with your Pro-Q 3 license key? I'm afraid that will not work. You can find the Pro-Q 3 installer here:

Nope, on my DAW it says FabFilter Pro Q3, and on the actual plugin, when I turn it on also says "FabFilter Pro-Q 3 Evaluation".

In that case it's best to send us an email with a small video of the issue. That way we can see what's going on and provide you with your license key if needed.

Will do that just now, thank you.

says the message size is too big when I include the video, should I do screenshots instead?

I have recently bought a new pc and trying to re-install and activate all my plugins but when I try to active the Pro Q3 license i get a message saying "The specified activation code is invalid. Please check if you've entered the code correctly! FabFilter activation code only contain letters, no digits." even though I copy pasted the license key from the plugin boutique website and tried to re-write it by hand and it still says the same thing while not allowing me to activate it, any help please?
Thank you.
