[wServer.exe] Crashing after adding new map/changing map

Hello im fil. I have worked on Realm P.Servers long time ago and i can't remember how to repair this error.
I mean this:

Code:

---

System.TypeInitializationException: The type initializer for 'wServer.realm.RealmManager' threw an exception. ---> System.TypeInitializationException: The type initializer for 'wServer.logic.BehaviorDb' threw an exception. ---> System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
  at static System.Void wServer.Program.Main(System.String[] args) in C:\wServer\Program.cs:line 46

---

This happens when I just replace a *.wmap file with own created.

All stuff in the code is addded and EmbeddedResource is set too.
I extents the Trapped server.

If anyone know how to repair that error, please answer here or send me an email on fil_rotmg (at) outlook (dot) com
Regards,fil.

Every error is repaired by checking what caused it. There is no memory involved

You're right, but I know that I had that error, time ago.(or maybe not :x ) Any help ? ))

Sorry for double-post, but someone know how to fix that?
