Thanks for the reply.
Is it safer to have the wallet on BOTH Blockchain.info and Multibit? Or ONLY on Multibit? How would I make it so that my wallet would only be on Multibit? Is it as simple as making a new address in Multibit and sending the BTC from Blockchain.info there?
You need to make a completely new wallet and then send all of the coins into an address from the new wallet.
