I am getting really concerned about this. I have over 100 coins tied up on SDice. I had a problem with not being able to log in, and started an e-mail correspondence with them 2 weeks ago. At first they replied (although not to PM here), and requested I sign a transaction, which I did one week ago. Since then, silence despite me sending multiple follow up emails. 

I invested 2 weeks ago for the first time ever, would be really unlucky if after years without any real issues they picked this moment to abscond!
