If the Lyris Server was previously working for you, then crashed, it is likely that you have found a bug in Lyris.
Before you do anything else, make a backup of all the files in the /lyris/db/ directory. This will ensure that you do not lose any data, and it will also enable us to recreate your problem.
Try running the Lyris Server again. In most cases Lyris will crash again. The reason for this is that Lyris does not mark a job as finished until it has completed successfully. This is so that Lyris never loses mail and all jobs are completed to success. However, when a bug in Lyris is found, this also means that you cannot proceed until the bug is fixed.
If Lyris crashes when you run it again, fill out a bug report form at http://www.lyris.com/forms/ with the subject "Crash Report". If you were doing something out of the ordinary, describe what you were doing.
We will then contact you, either to give you a version of Lyris which fixes your problem, or to obtain all the files from your /lyris/db/ directory so that we can recreate your problem and fix it.
