In the EU software licenses can be resold regardless of the developers country of origin.
The July 2012 judgment in the ‘UsedSoft’ case stated, in summary, that the distribution right held by the software vendor was ‘exhausted’ within the EU provided certain conditions were met: that the software license was perpetual, that it had originally been sold at an economic price, and the seller’s copy was made unusable at the time of transfer.
The European Court restated this position a couple of year’s ago. The original judgement involved some well-know software vendors.
However, Roon is not software in this sense, it is a subscription service (a membership.) Or at least that’s my interpretation. Maybe @danny has some worthwhile advice afterall … he certainly understands customer service.
