Problem with ResXFileCodeGenerator

Question

Hello everyboy,

sorry for my english but i will try to do my best.

I'm developing a window application with visual studio 2005. I have a folder that inside has a resx file that contains
string messages in english language. Then I added the other resx files for the other languages and the application
runs correctly but on builging project i have warnings on the resXFileCodeGenerator.
The wargning are like these:
Warning    24    The custom tool 'ResXFileCodeGenerator' failed while processing the file 'HMI_Msg\HMIMess.bg.resx'.   
Warning    25    The custom tool 'ResXFileCodeGenerator' failed while processing the file 'HMI_Msg\HMIMess.cs.resx'.   
Warning    26    The custom tool 'ResXFileCodeGenerator' failed while processing the file 'HMI_Msg\HMIMess.da.resx'.

So my question is: if at run time the resources manager find the string in the correct language that i setted, what' s the
problem during building project? Are the resx files non in correct form? How cuold i check this? 

As i said this warning isn't blocking my developement but i would like to get out it.

Thanks a lot for any idea.

Luca
