I haven't used multibit before, but it's abandonware and no longer updated now. Your best shot is to get your private keys out of Multibit if you can and use some other supported wallet instead (given that you managed to find this board, you should already that Bitcoin Core and Electrum are options).
I bolded the last part because it's extremely important. Whatever you do, do not uninstall Multibit until you exported your keys in plaintext, or you might lose access to them according to the quote!
Do NOT use Multibit to encrypt your keys.
Even it can't decrypt its own encryption.
I know because I have such experience.
You, the thread starter, are better off exporting the keys and encrypting them directly on your own, like using WinRar or any encryption software that you know to be very reliable (anyone who says WinRar is unreliable and/or untrustworthy, please state the evidence proving that is so).
Different wallets may use different methods of encryption and so decrypting the keys may not be compatible between different wallets.
Multibit is no longer supported now.
You have been warned.
Edit:
I was lucky I didn't uninstall my Multibit after encrypting my keys with it, so I managed to export the keys unencrypted, and encrypt them myself.
Or else, I would be in seriously deep shit.

Thank you very much for your reply!! I have the keys extracted from my multibit wallet and they are on my laptop but they are still encrypted. Is it possible to import them into Electrum for example and try to decrypt it there?
