Thank you everyone for your kind responses.
My card is resting in rice at the moment but, to be honest, I'm a bit hopeless about it.
I think that the memory module in the card might not be damaged and that a recovery performed by spe******ts is possible.
Since Olympus is responsible for the damage in the card, I will talk to them to see if they can pay such recovery (and I'm quite hopeless about this also).
I will let you know what happens at the end... Thanks again!!
