I had the same problem with their slack and asked them on twitter. After 2 minutes I had the answer. They told me that they are working on this, and even if you get this error they send you a e-mail (check your spam also). In their telegram group they gave me this link: https://edgelesscasino.slack.com/ and this one worked for me. Or just write them on twitter, it looks as if they are really active there.

Yes, a beta version is a good news for this ICO, that makes the supporters to keep their choice.

EDG is growing up higher than yesterday and it 's still on the race .
The volume is also higher and I suppose that there will be some good news released in next days. I will never miss this chance.

Due to the intentional design of our Escrow for the token sale, we must complete all of the returns to all of the sales since we did not hit the sales minimum. Because we intend upon launching the token anyway to honor all of our token obligations to all of the Employee, Marketing, and Code Bounty Pools, we have received notice from the vast majority of participants to get remain part of the token release. Since we have to close the original sale to process the refunds per the Escrow service, we will be holding a one day token sale "buy-in" for those participants who wish to remain part of the Embermine token distribution.

All purchase refunds will be happening on Monday automatically to the Bitcoin addresses provided by each buyer during the crowdsale. As we are processing the refunds, we will also be notifying everyone of the exact particulars regarding the sale, the timing, cost, and procedures to follow.

Thank you to everyone for their support. Here are the preliminary details regarding the sale:

Essentially, we are selling the tokens now at .0000004 BTC each, or 100X original value.
The original minimum purchase was .005 BTC which got the buyer 125 Embers. That same user now gets 12,500 Embers
This looks to be the token goals:

Target number of Embers to be produced: 58,823,530
Distributed to Token Sale buyers: 50,000,000
Total Distributed Outside Of Token Sale: 8,823,530
Distributed to Employee Pool: 3,529,413
Distributed to Marketing Pool: 2,941,176
Distributed to Code Bounty Pool: 2,352,941
Cost per Ember: .0000004 BTC each

All existing buyers will be guaranteed at least their initial commitment. We will guarantee that at least 50,000,000 tokens will be funded through this process, to ensure that all Employee, Marketing Bounty, and Code Bounty pools are properly vested as intended. This is not intended to be a replacement of the original token sale. Rather, this is the method of release we are doing in order to get our initial token created as we begin development and allowing those who want to see this project succeed to still be involved.

Because of the format the sale will take, this will be an invite-only event where someone must receive the link from Embermine or a current participant in the token sale. Each participant will receive a special link that they use in order to participate. There, they can claim their original tokens or participate at some other level. Once someone participates, they will receive an email confirmation of their order and a referral link that they can send out to another who may wish to participate. This process is to ensure that those who originally participated will still have the earliest opportunity to participate in the sale.

NOTE: These are just the preliminaries. We are working the details out with our Token Administrators and our Escrow partners and will let everyone know as soon as the details are all finalized. Some of these elements will change, but we are hoping to run the special token sale on June 6th.

Thank you to everyone for their support!  

you are telling the true. not only the bounty hunters anger about the exchange rate being change, the investors in April also don't like this change ..
