I have been made a creditor and may be owed money by my previous employer

So about a month ago I woke up from my days off to have two pay checks, one with my previous weeks work paid out and the other with all my holiday pay and days in lue A couple of phone calls later I found out the the restaurant I worked for was closing that Saturday and I would still be paid the the last weeks work. I worked the last week got paid ect.. I thought that was the end of it I just received a 44 page email from a liquidation company naming me as a creditor. Alot of the paperwork is a bit confusing because I'm not sure what I'm looking at. From what I can gather there is a meeting taking place soon to discuss the company's displacement and the destruction of will company books ect. And the other part being they owe me money(i think) Can anyone explain the process so I know where to go from here
