FreeRapid Downloader won't load frd.odb

All of a sudden my downloader stopped loading.
It says Fatal error. This is unexpected error, which can lead to application instability. An application restart may help. Please report this error to the authors.
I have restarted the computer, tried the new beta and I don't want to
lose the information and the finished download items, so that I don't try to download the same thing more than once.
The frd.odb is still there, but it is quite large and the links.txt
Hope you can help me get my database readable again.
Thank you very much,
Anita
