You are in a queue, so taxman comes first, then the bank, then accountacys etc, and finally those like you, by now they is no money left, you need to assume the money will not come. Speak to your accountant, and/or start working out how you can recover from this.
This is a warning to all, the cre3dit crunch is biting and people will delay paying you, never stretch beyond what you can cope with, but that is always impossible to do
