essential upgrade

hi all,
Iv’e taken a quick look around and cant find the answer to this question, so, can I upgrade my cubase essential 5 with a cubase 5 upgrage that is being advertised on ebay, the seller says its a pucker update but with no dongle or product key, will it work?, cheers jd.

Buyer be aware!!!

You will need a dongle with a valid licence, if not it’s a crack!

I don´t know what “pucker” means, but you do not generally need a dongle for an upgrade - you already have one with your essential 5. What you do need though is a valid non-used license activation code. I personally would rather not buy it.

thanks guys I sort of knew that would be the answer, you gets what you pays for eh!
