Hey!
This is probably not the best place to find a solution for that but we can try. After reading a bit, I assume you were using a program such as Book Library by WenSoftware to manage a collection of books. Am I right? What happened to your software? It now crashes? The license expired or other?
At their website it says that the software is able to export to ascii and html, that would be your best bet. The software has a limitation of 50 books max, so I don't know how it work if you open your db in there.
What software did you used before?
