The full error is:
My.Application error BC30562: 'Application' is ambiguous between declarations in Modules 'Videstra.My.MyProject, Videstra.My.MyProject, Videstra.My.MyProject, Videstra.My.MyProject'.

I'm at a loss for where all of these modules are located or what to do about this. The result is that all calls to My.Application.Info.DirectoryPath returns a null string on execution, but shows the above error when debugging.

It seems to be identifying 4 modules with the same name, but I don't know where to look for what look to be duplicate declarations...
