Cannot Activate Particle brushes

Hello, I bought the particle brush set for flame painter but it continues to say demo/preview. I sent a pm to your Facebook page, no reply. I sent an email to your support team, no reply. I don't like leaving negative reviews, but I am now posting in a public forum in the hope that you will reply. Thanks

Hi @emmanuelspori,

thank you for purchasing the Particle systems bundle!
Both Flame Painter 4 and the bundle are registered under the same email address so everything should be working for you.
Please restart Flame Painter 4 and check once again if they are still in preview mode?
An active internet connection is required so that the server can check the license and unblock the preview mode.
