You get this message when the .pdb file was not found or is not compatible with your dll version.

Try doing the following:

1) Check if the .pdb file exists in the same location as the .dll or in Visual Studio's pdb file directory.

2) If it exists, try manually loading it - right click on the module and select load symbols from.

3) If you get an error saying the pdb is not compatible with your dll... well... it means just that. You can either recompile or try to find the compatible version.
