Ive been using multibit classic since 2012. I wasnt aware until recently that its no longer supported or updated by devs. I had a large transaction sent to my wallet, and when I tried to load it I get this message

Unable to load wallet "C:\Users\laura\AppData\Roaming\MultiBit\multibit.wallet" or backups. See help on "Wallet Backups" for more details.
The error was "com.google.bitcoin.store.UnreadableWalletException Transaction did not deserialize completely: 4f3aba81fa59833a2d22b87f7f95872944d7fffbf5a3866cb12b4c6ed47badae vs 0c476c959391a1e2863ce7580110061f9418b5dd88e53bcff6ba199630338982

Could not load the wallet file "C:\Users\laura\AppData\Roaming\MultiBit\multibit.wallet".
The error message was "null"

Any help would be greatly appreciated. I tried going into files and deleted Wallet.spv file. Ive done this twice now and waited for hours for block chain to reset.. However it still isnt loading my wallet. Any help would be greatly appreciated. Id like to move to Electrum but I cant do anything until I get wallet to load.
