Possible Reasons :
A. Your PC's Windows registry contains an FL Studio username, but the registration code for your FL Studio is not updated.
eg. this can happen when you downloaded & installed a new version of the FL Studio software without getting a new updated registration key.
B. You are using an illegal version of our software!
Solution A:
1. Download and install the latest FL Studio demo program.
2. Login to your online Member Profile account
3. Download and run a new flregkey.reg registration file.
4. Both the FL Studio program and the registration will be for the same program version now.
Solution B:
1. If you don't own an official copy of our software, please buy it from our web shop or at a reseller.
By using illegal copy of our software you endanger the future of FL Studio. Since you are using it and taking the time to investigate this error, please do the right thing and buy a copy.
Also, by buying your own copy, you will become a member of our user community that will allow you to watch our videotutorials, participate on our forums, download extra samples, get real support and (in case you by the download version) even Life Time Free Updates for our software. So this deal is a legitimate steal, don't wait any longer to buy your own copy.
