Thank you for your suggestions the address is
1DMMWLxY7x2zeF7oz7UHoyf9PfDRcfbEwe

I am not sure if import / add is the same thing in bit coin talk but I went to "receive money" and pressed "New Address" a popup window asked me for a label and do i want to make the label public, i didnt check that.
I then get shown the default address and my newly created address. I copy / paste the newly created address and send it to my friend.
2 days later he makes the transfer and when i log in its like someone else (or a bug) has gone in and delete the address from my account. I am only left with the default address, my newly created and labeled address is no where to be seen. Vanished.

I didn't get any private keys / public keys

I have contacted blockchain.info and they looked at the backups and said they can not find that address associated with the account. They said without the keys they can't do anything. The support person has not responded in a while so if they do come back with an update I will let everyone know.

So to me the only options are
1) Their system has a serious bug, creating legitimate addresses but not keeping them associated with the correct account or releasing them randomly.
2) Their system is compromised by a hacker
3) My computer has a virus, which I checked with multiple virus / malware programs and all came back crystal clear.

Thanks to everyone for their help / suggestions.
