I have had the wallet problem as well. Out of sync and no connections.

Perhaps it was when we hit 185000 block?

Edit - I've tried deleting and reinstalling the wallet, deleting the roaming folder (obviously keeping a current backup of config, wallet.dat) and now my wallet is still out of sync - no connections and to top it off, instead of all my coins (approx 54000), it shows I have just over half unconfirmed (29000) so it seems I've lost around 24000 coins.

I've tried the 'repaid wallet' function and it just tells me it's true. Perhaps when I am connected to nodes and the wallet syncs up again the wallet will repair? I hope so!

Not sure what the problem is now but I hope I've not lost my coins.
