Hello Matteo,
Let's try to filter your questions:
1) I don't understand what you mean for "buying a new licence" (sorry, my bad) for 20 euro. If I understand it correctly I would not be requested to buy the whole products (in my case VEP5 and the S Edition) that is more than a thousand euros but a 20 euros licence for every library or product I owe, am I right?
=> If we know that the license is stored on a key that does not work anymore, we also know that we can hand out a replacement license. This replacement license is 20 EUR.
2) I didn't knew about an insurance for your libraries/licensers: in my case, the key, that is perfectly working is older than 2 years (2014). What is your raccomandations or plans available for any incident that actually can happen?
=> You should get a new key every 2 years and transfer the licenses onto this new key. This way, the hardware warranty will allow us to replace both the key and the licenses without any costs, if it fails without any signs of misuse or damage.
3) Having a second key with a copy of the licenses?
=> No. It is all about copy protection. You cannot copy licenses.
4) Should I buy a new key and "transfer" the licenses from the older to the newest so that I'm again in a renewed warranty period?
=> Yes.
You are also correct that iLok has a different system. We all hope that we can come up with a better solution with eLicenser/Steinberg, and we rely 100% on their help here.
Right now, we are working with the available possibilities.
Best,
Paul
