solution to resources files

 I am trying to find any solution in the importing process of one of my projects developed in VS 2003 and I couldn't find it !
The problem is with the names of resources files. I read about the difference between names in VS and MD but I couldn't find any guide to the solution, Can I make some hand working renaming files , to solve the problem ?

The errors are like:

Could not find any resource appropiate for the specified culture or its parents. Make sure "Proyecto.App.Splash.resources" was correctly embedded or linked into assembly "Proyecto"

and my resource file in monodevelop is Splash.resx

thanks in advance !
