I am having this same problem. I waited until 4.2 to even start and it was working fine until yesterday. Then I downloaded the new admin console (3.8 ) and used it to make some changes. Then I started having troubles with the database (errors starting the admin console) so I decided to trash the db and start over. Did that and now, boot5zones.bat crashes. Very frustrating as it was working fine this time yesterday. I haven't changed any of the .ini files or edited the .bat since I first got it working. Yes, I moved spells_en.txt.
***edit***
fixed it...had to use db.sql from 4.1
sure wish I knew what broke it LOL.
