Update and warning for you didger -
I asked Steinberg their policy and they said that because most of the licenses on this USB Key were Steinberg, they made an exception and provided the VSL activation codes, whereas if it was all VSL licenses the request would have to go through VSL.
My advice, which I've just done now, is to buy a new Vienna Key every 2 years and transfer all your VSL licenses onto that. It's a PITA but at least it beats pulling your eyes out with anger at the extreme cost of lots of replacement codes. With your spare dongles, you could make a nice necklace. Or use them for temporary demo licenses.
Anyway surely in a few years everything will be in the cloud... no more USB pains, we can hope....!
