Well... now I can see and compare things. Here is my explanation...
U saw the message when the Tx was not confirmed. Blockchain.info somethimes show this when multiple unconfirmed Tx are going out of an address, which is normal from a real time gambling site. Now, u saw that first.
Here begins the second part. Blockchain.info is distributed by cloudflare. Cloudflare catched that message as static against your public IP and hence keep showing it to u even when the Tx has got confirmation.
...This is what I understand out of the whole fiasco... may be wrong. If it is correct, then u log out, have a drink, have sleep, come back after a few hour and login ...u'll see everything is fine with this address... Just like what we are seeing now.
These txns were over the last 2 weeks - I havent been on updown for 3 days - all of the winnings txns from them over the last two weeks are showing payment address n/a and when I click thoough the txn ids on block chain I keep getting the 'double spend' warning in the image I posted.
I now find that when I refresh the page the warning disappears - but then I click on a few more red links and find another. Even more worrying. And my wallet is 2 BTC light at the end of the day - so there is a BIG warning sign here.
