Problem with multibit - please help

[semaforo]

  Hi, I'm getting some strange behavior with multibit. I just installed mac os x on my macbook after having compatibility issues with ubuntu, with which I was using electrum.

  First, I sent 4 BTC, and it worked fine.

  b6b59690ecd9cc330698120543752bc706ac89bf3e6ff9e3031453d11ac87324: Seen by 4 peers. Appeared in best chain at height 240119, depth 564, work done 909573329246568448.

Then, trying to finance a sell on localbitcoins.com, when I copy and paste the transaction it shows up like this

 9294bbdc0ae082d7492b57dcb0c73ef626709f5d6150996f9f9c1760ed3e396d: Seen by 1 peer.

   This was three days ago, and still not seen in chain?

  Also, my balance shows up as 48.584269 BTC, but I have only ever deposited just under 45 BTC to this wallet! Of the 48 BTC balance, underneath it says the available balance is 40.9148, which is exactly the original balance minus the 4 BTC I sent.

    Any ideas what might be going on? Do I need to resend the transaction that was not registered on the chain? What do I do about the weird balance/available balance issue?

 Any help is much appreciated!

In the help there is a section - in Support - for if you send a transaction and it gets stuck on 'Seen by 1 peer'. Have a read through that.
