I am trying to get started mining bitcoins with my MacBook which has a NVIDIA GeForce 9400M GPU.  I am using DiabloMiner and am mining as a part of Slush's pool.  I get the following error message when I try to run DiabloMiner:

What in the world does that mean?  I can't find anything related to it on the internet except for a paste on pastebin which is essentially my error.  Someone else then must be having this same error.

Thanks in advance.

Try searching with various terms on the internet rather than just posting the error message. Post here more, spend over 4 hours, get out of the newbie jail and post in the tech support forums.

I thought I had searched thoroughly on the internet for my error but I guess maybe not.  Just now I happened to look on the issues tab of the DiabloMiner GitHub page.  There was my exact error.  The developer had simply admitted that it was a bug.  The date says that the issue was posted a few months ago.  I posted a comment saying that I had the same problem and gave the arguments that I used when I invoked DiabloMiner.  I hope that the developer fixes it soon.  The weird thing is that my search engine didn't find that when I searched for my error.
