I bought an upgrade from cubase al to artist 10.5 and....

Well it never advertised that it came with a dongle. I didn’t know this and ordered a seperate dongle. I only need one. My question is, in what kind of container should i return it with?

I think you should keep it in case you ever need to use Zero Downtime.

I suppose if you wanted to return the extra dongle it would depend on who you purchased it from and what the return policies of that distributor are.

Got it from Amazom seller. They emailed me and agreed to a refund but is a simple envelope alright to send it back in?

I suppose the “Amazon seller” would know the answer to that question better than any forum member.

You’re right but after giving up that time and money people tend to think cheap.
