Don't bother. The money is never coming. Move on to something else quickly.
Wage theft is also a crime, and you can go through the police and district attorney to pursue that, if you can get them interested.
It's possible that the wages may be recoverable from the individuals even if the corporation is bankrupt, although how much time and effort you want to invest in that, I dunno. Would depend on the amount owed, I would think; I've not been in the situation, but I'd like to think I would stop working at a place where a paycheck bounced or went missing until that was resolved; with maybe some amount of flexibility for a paycheck a couple days late, or a really convincing explanation about why what happened happened, and how it was going to be resolved. Anyway, I don't think I'd be willing to make a big fuss about one or two paychecks, but I'd certainly file a report.
Contact whoever does wage theft prosecutions in your area if you've done work and haven't been paid.
If you've been paid until now, and are otherwise happy, tell them to let you know when they've got money and you'll consider coming back. But, don't promise to come back, and don't accept any promises from them. If they ran out of money before they got funding to continue, then any funding they get isn't going to be on good terms, and they may not be able to keep any promises they make.
