Same here...
Fresh install attempted 3 times on Win7 Premium.
Still getting... "errors" : "WARNING: Checkpoint is too old. Wait for block chain to download, or notify developers."
Post a screen shot of your client. Make sure you're running v1.1.6.4.
But in the meantime...make sure you do a fresh install like so:
First, make sure you have a backup of your wallet.dat file.
Next, a fresh install means taking out your wallet.dat file from your AppData/Roaming/CryptogenicBullion folder and temporarily putting it on your desktop, then deleting the AppData/Roaming/CryptogenicBullion folder and everything in it. Then run the client. Once it syncs and you are not getting the checkpoint message then close your client and replace the new wallet.dat the client just made with the one you temporarily placed on your desktop. Then run your client and allow for your balance to confirm once the block chain is scanned.
