Bukkit

What steps will reproduce the problem?
1. Deleting DynEcon folder
2. Deleting config.yml
3. Reloading server.

What is the expected output? What do you see instead?
I want it to change the config to the right one, but it keeps reverting to the previous one, even if I delete it, place the new one, and reload. The old config comes back. I have no idea why.

What version of the product are you using?
v.9

Do you have an error log of what happened?

Tell me if this helps:

Same problem as me.

Try v .9.01

Still doesn't work. I tried deleting the whole plugin and it's folder, stopping the server, replacing the new .jar and folder with the new config, and restarting the server, but it still reverts back to the old config. It still won't let me use /buy|sell command even though I have it enabled in the config...

@dingousa: Go

Please try v .9.1

Thank you, it works now. :D
