Banks Are Reversing PokerStars Checks

[pe2]

In mid March I deposited 2 checks from PokerStars. I believe they said WellsFargo on them. The check funds were then available and used by me.

Yesterday (almost a month later) - I notice that my available bank balance is hundreds less then the balance. I call the bank and after waiting on hold a while the lady tells me that the funds are being reversed and/or on hold until June 10th because the company that issued them is being investigated for fraud related to gambling.

I'm not sure what is going on here. Is there anything I can do?
