Everyone on your site is complaining that they have placed orders and have no confirmation of payment. Why is there no confirmation of payment and you stopped accepting Paypal or debit cards? You need to be more professional, I want to make big orders, but everyone complains on your site they have no confirmation weeks after payment. How are you dealing with this?

The type of seed electrum uses was changed in the 2.x versions. You can download an old 1.8.1 version of the wallet here and import your seed into it. I think the latest version of electrum could then use the wallet file the 1.8.1 version generates. If not you can always export the private keys from the 1.8.1 version and import them into the latest electrum.

ThomasV says version 2.0 converts wallet files from older versions into a different format.

I suggest making a new seed in the latest electrum version and sending all your coins to that wallet after you get back control of your coins from your old wallet.

It's best not to try sending coins directly from a 1.8.1 version wallet because the network might not accept them since its (s values) rules changed. Import your wallet or keys into the latest electrum before sending coins through the network.
