Yes, i have tried and sett it of that and i am able to start Node Editor and use it all without any problems so the shortcut command is no a problem.

The only thing is that when i Right mouse button click in the Node editor i can access and create Nodes but when i click on Macro i just get that error instead.
It seems like it might be some bug or something because i did try some of older version of Node Editor, v0.9 i think, and there was no errors. In Node Editor v1+ i am getting that error problem.
