Don't want to thread jack but I feel this sounds like a problem I am having at the moment as well.

I installed Electrum 2 nights ago from a link (Version 2.1), created a new wallet, saved the seed address. Used my receive address in my mining .bat file and started mining. The next day I noticed Electrum wasn't connected. No matter what I did it wouldn't (only listing one server).

I reinstalled Electrum from the actual electrum website on my main laptop. This was the latest version and it connects to servers now. I copied my wallet from the mining rig, there was only one wallet called default_wallet.
What was strange was the file opened without asking for my password or anything. None of the address matched and my old address wasn't listed under changed. I then tried to open it from the Seed address I saved the night before. Same issue/address all with no history. Although i may not have any history or funds yet I would still like to see my address from the night before to make sure.

What is odd is none of the new addresses will work with the miner. As soon as I change the .bat back to the old address it starts working again. So I cant even start again with one of these new addresses and I cant access my old one.

Possibly the same issue as OP which is why I thought Id mention it here rather then a new thread...
