Looks like it is just Coinexchange fixing the wallet still, saw this post today in the community... Just a matter of time now, Coinexchange have been busy with website maintenance, which is now finished, so now I'm guessing they have time to maintain their client's wallets.

E-Mail from coinexchange:

Hi xxxx,

The BTDX wallet is currently disabled for maintenance. Our tech support team are actively working on fixing the issue and getting it back online asap. Pending transactions will be processed once the wallet is re-enabled. We apologies for any inconvenience.

Sincerely,

CoinExchange.io Support Team
