I just bought a second hand Presonus Revelator io 24 and I'm looking up how to use it and apparently you have to register it with purchase date and serial number in order to use it, but I have no idea what its original purchase date is and when I tried putting in a random date with the serial number on the bottom (in the picture, it's under "manufacturing date" but that's the serial number, right?) it said serial number not valid. What do I do? Do I need the account of the guy who sold it to me to use it? Can I use it without registering it? Can you even use it with softwares other than StudioOne?

Thank you so much, this is the first audio interface I buy and I'm confused
