I'm running the latest version though and it doesn't look like a new one has been released recently ... wallet can't sync, said it was 3 hours behind when I woke up (about two hours ago), and now it says it's 5 hours behind ...
What happened at ~7:30 AM EST? Any news/fix/solution to this?
Had a quick look at the source and it seems that message may be displayed when you fork. The network seems to be producing blocks still; last one minted around 7 minutes ago, block 87450. Have you tried quitting and restarting your client a couple of times? If more than one node has forked with you it may take a couple of goes before you get the right mix of peers to get you back onto the main chain. Having said that, I cannot see any obvious fork.
