Creating C++ Pawn, getting file location error

Hi…
When I am creating a new C++ Pawn Class I am getting an error in the dialog box that says:
All source code for ‘project name’ must exist within “Engine/Binaries/Win64” directory.

I’ve deleted directories and did a regenerate project files…still no working. I don’t remember doing anything, but I must have. Suggestions welcome. Thanks!

where are you creating your c++ files, for example: ProjectName/Source/ProjectName/Here.cpp?

Its under ProjectName/Source/ and then I’ve got some folders based on type…easier to find things. Use to work, not sure I said that above.
