Even if there was no possibility to get money back from the liquidation, I would ALWAYS communicate my credit.
In fact, if you are thinking of any kind of claim, you SHOULD communicate your credit, so you can prove you've done anythin in your hands to get the money back and, on top, that the co-liable for the money is able to claim back Huma.
For instance, if ypu decide to sue the Bank that received the funds in the special account (something we highly reccomend), you should communicate, so the bank takes your place as creditor against Huma.
And the same can be said if you decide to sue your ex-solicitor for negligence for not advising you properly about getting Bank Guarantees before paying.
In any case, communcating your credit is a matter of diligence, from our point of view.
So, our advice is: COMMUNICATE YOUR CREDIT and SUE THE BANK RECEIVING THE FUNDS THROUGH THE SPECIAL ACCOUNT mentioned in the contracts.
Best regards and good luck
