Samplitude: Valid serial number accepted then rejected. Error code -14

I installed Samplitude Pro X4 Suite and activated it successfully using the serial number that Magix provided. However, when I exited Samplitude and re-opened it, it asked for my serial number again, and then rejected it. So first it accepted my serial number, and then it rejected it.

Here's the error message: "The serial number you entered is invalid or may apply to another product. etc ... Error code -14."

That seems to indicate that I am using the wrong serial number. However, in my case, I have already activated and used Samplitude with the exact same serial number on the same computer. That is, the serial number is initially accepted, and I can use the software. It's only when I exit the program and try to re-start it that my serial number is rejected. I have uninstalled and reinstalled several times, but the problem persists.

I wonder if this problem might be a result of having previously installed a demo version of Samplitude Pro X4 on the same computer. Perhaps the CD version that I installed subsequently did not properly remove the demo version.

I'm going to answer my own question, because I've solved the problem on my own: In the Windows Control Panel, I uninstalled not just Samplitude, but Independence, Magix Content and Soundpools, and Magix Speed burnR. I also deleted any files in my Windows folder that seemed related. In addition, I deleted all related registry items, which I do NOT recommend because it's extremely risky and probably was not necessary. (If you modify or delete any registry items, you can corrupt your Windows installation, and your computer might not be able to restart.)

Then I re-installed Samplitude Pro X4 Suite from the backup CD. I activated it using the usual serial number. To test the installation, I opened and closed the program several times, and opened some VIP projects too. It works.

Note to Magix: The installation executable should check the computer for any conflicting old versions of the software before starting installation. That's just common sense.
