I am assuming it does not matter if the next relaunch is in an hour or a week, the owner has already guaranteed refunds if the second launch fails.
I am assuming I have some time in order to request the refund, even if it is after Sunday when the relaunch occurs.
Im not sure you CAN apply for a refund. Legally, Mr. CEO owes you nothing unless you have a clear contract mentioning the deliverables, signed by witnesses and paid for in the national currency (USD in this case). Its like the situation of people pre-ordering bitcoin miners and paying for with bitcoins... you are essentially crossing your fingers and trusting that one fine morning the bitcoin miner will show up at your doorstep in a FedEx package. Legally they owe you nothing, because nothing was paid in USD. And it did happen.... lot of people did not receive them. "Bitco Miners" is a good example.... just closed down their website after raking in enough bitcoins and disappeared.
I'm afraid you all are dependent on the goodwill of the dude. Sigh.... I feel for you. Non-responsive, MIA, all point to the wrong direction.... and to add insult to injury, the value of bitcoins decided to pop its head back up and going upwards!
