Access is denied to a folder in one class, but not another

Question

I get an exception when trying to rename a folder with this code:

Directory.Move(@"D:\MyOldFolderName", @"D:\MyNewFolderName");

An exception:

System.IO.IOException was unhandled
  Message="Access to the path 'D:\\MyOldFolderName' is denied."
  Source="mscorlib"
  StackTrace:
     at System.IO.Directory.Move(String sourceDirName, String destDirName)
     ...

The fact is that the EXACT code line works in a different class of my application. An application consists of only one DLL.

What's going on here? Any ideas?

Additional Information:

• The application is a WPF application using the MVVM design pattern.
• The class in which the folder is renamed. Works with ViewModel.
• The class in which the folder is renamed DOES NOT work, this is a helper class (the method uses some databases before trying to rename folders).
