I just got myself a Korg Oasys, but unfortunately, it isn't booting.
I was aware of that, but since the price was great, I just had to go for it...

So now, I was really hoping to get it back to work!

It seems to start normally before a blue screen shows up telling it needs to be re-authorized...
Since I am not the original owner, how can I get that done?
It also came with a set of original Restore CDs, if that helps...
I would later on like to get an SSD installed and I know it is missing a screw in the screen and one of the keys is not working, but for now, I'd be more than happy if I could just get it to work and do some extra maintenance later on

Thanks in advance and best regards to all!
