I bought a few copies of EthOS and it worked fine until today - Now they sent a message on the Stats Page and locked it. If they think you have made a copy and did not pay they shut off access to the stats.
I bought a few copies and also bought a couple of rigs that were made already and they had it on the system. Now I cannot use any of them and you want me to send you receipts and ask for permission.
I will be doing a chargeback on all of my copies of EthOS and would recommend others to do the same.
