Needing Help With Regards To Automated Software Testing

The company where I used to work for before is offering me a job.  They need somebody who knows the system that I handled.  They are having problems with the new system and some of the areas have been corrupted and they risk losing some of the date files that are needed by the employees. 

Even if I wanted to help them, I have a life now and Automated Software Testing is not included in it.  Although I told them that they give the policies to the programmers, the ones who are modifying the program and start from them.  Always give a run down and test from the start to finish. This testing should include the people who are going to use it and the people who are doing the modification and of course, somebody from the company where they bought the software from  as well as the software for testing.
