For whatever reason your file is corrupt, the MW database.
Please use the installer to re-install a copy of the database, and the error should go away.
The installer by the way runs much like the installer that you ran to install Spooky2. However, it doesn't ask nearly as many questions and knows where to place the file.
Just in case,
A few get trapped by taking what they download for the MW database, and copy it into the Spooky2 directory directly.
This file downloaded actually is a compressed archive that has an executable installer inside.
One will need to extract this file and run it to get a copy of the database installed correctly.
