I have updated my Electrum wallet from 2.6.4 to 2.7.2, and it has deleted my wallet.
I created a new one from my seed and have added 5 private keys from my old original Bitcoin wallet, which I have been using for years, using the instructions here:

http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

The process has arrived at a box marked Install Wizard which says Please wait...

Nothing has happened for several hours. How long am I supposed to wait?

I have stopped using the Bitcoin Core wallet, and I have imported 2 of the private keys into Electrum, which works fine, except that these addresses aren't included in the wallet seed.
Can I do an internal transfer to move my funds from the imported addresses to native addresses in the Electrum wallet that are supported by the seed?

Recently on Bitmessage there was mention of an altcoin called Spillcoin™.
It seemed to have its own Bitmessage channel: deleted
and there was a website: deleted

UPDATE: Forget about Spillcoin™. The website quickly disappeared, and it turned out that the whole event was just a big wind-up by Bitmessage trolls.

I have dumped 2 private keys from my Bitcoin-QT wallet, and they are in L**** format.
How can I get these keys in 5**** format, so that I can import them into an Electrum wallet?

I can't really transfer the funds, as they are mostly bitdust, plus I want to keep the same addresses in Electrum.

At the public library, I tried to download the Electrum client , but I was presented with this message:

I have mined and collected a small amount of altcoins, which I would now like to give away to a worthy cause.
I have: 1 Litecoin, 8 Terracoins, 5 Freicoins and 20 PPcoins.
I don't really expect anything in return for them, but I would be thrilled to receive a very small donation of micro-Bitcoins in exchange, if someone was feeling generous.

This is my first post, so please be gentle with me.

I have installed the Litecoin-0.6.3c client on Windows XP, and downloaded the blockchain up to date.
I created a file called litecoin.conf, and put it in the blockchain data folder. It contains the following lines:

rpcuser=username   
rpcpassword=longpassword
rpcallowip=127.0.0.1
rpcport=9332
server=1

When I try to start the client I get an error box that says:

An error occured while setting up the RPC port 9332 for listening:
open: An address incompatible with the requested protocol was used

What have I done wrong, and how do I fix it?
