Don't be, it happens.
And yeah, you can do it one of two ways. Since GM8's import/export feature is fucking retarded and done horribly, there's little chance you'd be able to import my engine's stuff into yours (well, not MY engine, but you get what I mean). The other way, though a little more tedious, is simply having two GM windows open, and copy-pasting the code text from one to the other.
