Scorecoin issue - please help

[Dohnut]

on 25th January I sent some Score from Cryptopia to CoinExchange but it has not been received. It's definitely left Topia as it's on the withdrawal page and not in my balances page. I've checked the address I sent it to and that of CE and both match.

Could this be because of the recent change to POS? Did I send 'old' POW coins to a 'new' type address?

As you can probably guess I'm a bit nonplussed! Any help would be greatly appreciated.

Thanks
