MabiPro: The Authentic Old-School Mabinogi Experience

I've recently decided to boot up the good ol' MabiPro after a long hiatus. After booting, I'm met with an error due to my DB subfolder in my Data folder. I receive the following error report copied to my clipboard automatically:

I honestly don't remember much about the specifics of the sort of stuff I have in my Data folder, other than it was LazyFae's.

Here's some links to some screens of my DB folder:

If anyone knows what in particular might be causing this issue, please reply.

I suggest removing the data folder completely and start adding mods you deem essential to your gameplay. There seem to be a lot of mods and I am not an expert but I believe this will definitely help with your issue.
