"Progress" is the name of the company that provides the database & programming language (sort of like calling SQL Server and VB "Microsoft"). You are running some sort of application that uses those tools. It might have been developed in house or, more likely, it is a commercial package. I mention this because a lot depends on the application that you are running and how it was implemented. If we know the name of the application someone may know a simple way to restore and extract a specific company.
Otherwise the basic process is probably something like:
1) restore to some spare disk space.
2) write some custom extract code to dump the problem companies data.
3) write some custom code to replace the flawed data.
(and to do that you will need access to development tools or a consultant who has them available).
