Source updated with checkpoint for correct fork.
For people with windows wallets, go to help > debug window
Paste the following:
getblock 000000000055b9d4876d376097e81ce34506cf148d28b94af13dda0c73944341
if you get an error you will need to resync your block chain.
The current wallet on dropbox has the correct checkpoint on it. If you are on the right fork, the update is optional.
I am very, very sorry for the inconvenience. We'll get this sorted.
None of the fork in the correct pools!???
