This is some sort of bug on blockchain.info wallet. Can I ask if what character does your private key starts? If it's 52 characters that start with L and K then your public key is compressed, so all you need to do is uncompressed it so that you can get the 51 characters private key which starts with '5'. To uncompress it go to bitaddress.org and download the site, you can see the link below (GitHub repository link), run the site offline, and go to 'Wallet Details' paste your private key that starts with L or K, then get the uncompressed private key that starts with '5'.
hey man, I got it with your help. what is an address to tip you?
That's great dude, hope it helps a lot. Now you can trade your BCC in bittrex.
