Make sure that you open a support ticket with Cryptopia then. I have been recommending everyone to utilize our other exchanges like:

https://coinexchange.io/market/DNR/BTC

or

https://www.southxchange.com/Market/Book/DNR/USD

Both of those exchanges are running out latest wallet as well. Cryptopia has yet to reply back in any shape or form to update their wallet, seems like they could be turning into a Yobit (not updating wallets and not staying in contact with developers)...I don't want to jump to conclusions as they seem to be somewhat sorting out issues finally, and are probably very behind in support tickets, but the community should know that their Denarius wallet is not up-to-date yet and they are having delays in general for most coins.
