I sent some bitcoins to my wallet (Multibit V 0.5.18), then tried to send them to an exchange but they just get stuck and never arrive for over a day now
Here is the transaction which reports it correctly
https://blockchain.info/tx/503809ddfaff3ed9b970f8de835f39de297658622f94793c5abd364cbce8fd0c

However When I click on the transaction in Multibit it shows the correct amount sent but with a fee of 0.44355


I have since read that Mutlibit has been discontinued
Any advice on how to retrieve the coins and transfer to another wallet.
