There are 74643 blocks as I write this. The split is causing some network problems. You should connect your computers to each other with the addnode parameter.
I suspect there's some difficulty receiving blocks if all the nodes you're connected to are 0.3.9 or lower. We need enough of us so that at least one node you connect to will be 0.3.10. The problem will start to go away when we make up more than 1/8th of the network.
It'll help if you port forward so you can get lots of connections.
For now, can some people running 0.3.10 with static IP who can receive incoming connections post their IP? Then we can -addnode= them and make sure to connect to at least one 0.3.10 node.
