How To Generate A Dogecoin Private Key From Public Key?

Question: I own (used to own) 15+ bitcoin. Now my server has been compromised and is missing my wallet.dat file which is how my BTC was converted into DOGE when I downloaded the blackcoin client. Can you generate a dogecoin private key from the wallet.dat file in order for me to transfer any cryptocurrencies (BTC, LTC ect.) back into my account?

Thanks in advance!
