I think its cryptopia. I had the same problem last week and today i send to deposits and still nothing. Just wait u will get your ETN's on your account. Im wondering if i will switch to nanopool. I have used nanopool for coins like ETH and XMR but im now mining ETN on electroneum.space. Its very unstable but i guess i will not be mining ETN anymore after the ICO wallets get unlocked.
I'm really happy with the ETN nanopool, I'm getting exactly what the calculator says I should be with my 12.5K H/sec. rig, and it's been perfectly stable for me for the past week. But as you mentioned, it may become much less profitable than XMR in a couple of days, when they relaunch the wallets and people dump their coins. This is why I'm worried about my delayed deposit on Cryptopia, as I would like to trade for LTC or even DOGE, before the relaunch.
