All;
I am running E-Calibre on Windows 7 and love it. I finally imported and organized over 3,000 pdf books and papers and I can't do without it. All of a sudden I'm getting the following error whenever I try to open a book.

CantOpenError: unable to open database file

Has anyone seen this error before? I'm concerned that I'm going to lose my entire library. Any help at all would be greatly appreciated.

Thanks;
Frank
