Runtime error after first install 3.4.0.3008

[nznoip]

I downloaded and installed DAVID_3.4.0.3008 after i had updated .net framework to 3.5 version. But It still got the runtime error as you can see in the picture.
Somebody please help me out. Thanks.
By the way the word at first means 'at'. The platform is windows xp.

Are you sure you have installed DAVID correctly? This error may occur when not all files in the subfolders are correct, or for example when you mix files from DAVID 3.4 with files from previous versions.

Also it can happen when your Settings files are corrupt. You should try to delete all files in the subfolder "Settings".

If that does not help, it would be helpful to see the beginning of the error - please scroll up.
