Hi,
Sorry you are having issues. It is fixable! first thing is.
What is the file path to your macroquest folder? The reason I'm asking this is the Spell DB is auto generated by me and sent with the zip file you DL. There have been a few people that i've helped out with very similar errors and the issues has been every time where their MQ was installed. SQLite didn't like the path, and therefore didn't read the DB properly.
The solution was re-installing MQ at the root of any HDD you have. Example. D:\macroquest. I would try that first if you're willing and able.
If you need more help hit me up on discord, and If you even need me to i can remote in and assist that way.
