I reloaded the newest build of messenger 4.0 on a clean machine sql 2000 sp3a. Ran the script against a new database and edit the web.config. Added the directortory to IIS. Here is what I get:
Could not load file or assembly 'CuteChat.AppCode, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040).
I have never seen this before.
