Just a little update: I finally heard from the client, he gave me a story about how his phone broke, his mother-in-law has been sick, how people who owe him money haven't paid it and how none of the potential clients for the software have come back to him yet. He offered to pay part of the invoice now and part later. I said fine but I will apply interest to the invoice and he only has a further 30 days until the issue goes further. I wait with baited breath for the rest of the payment.
