I just checked, error 13001 is a missing database error, so here is my stock Database.
www.commanders-academy.com/luftwolf/DW_104_Database.zip .
Just unzip this file to your Dangerous Waters Database directory.
(This may have occured because of some JSGME related switching about on your computer... if the .ini file gets out of sync with the files, the tool can sometimes delete files you'd rather not have deleted, although I've never heard of this happening outside of human error, although its not always obvious what you did, speaking from personal experience... that is. My advice to you is to be sure your whole DW install is not bricked... it may be more than just the database... the good news is that enabling the Mod will make 307 work regardless, but stock DW might not function anymore)
Everything should work fine from there on, assuming it was just the database affected.
Cheers,
David
