I hate to be this guy, but this ICO and product is very likely a scam from the start.  See the link here:

They copied almost all of their code from a dice game already working on the block chain, called Etheroll.

Not only that, their house edge is  6.5% compared to etheroll's 1%.

Not only that, but they also hard coded in the bets to always be >47, giving them basically a 50/50 win chance on every single roll.

Don't believe my words though, check that link and also compare contract code on etherscan.io.
