Can't run matrix multiply sample

Also, maybe I misunderstand the term debugging, but I assumed with Nsight downloaded with Visual Studio 2010 professional, my code would be debugged real time. I still get errors (red underlines) when viewing any of the .cu files in the samples projects.

EDIT: Sorry, I was being an idiot with the first point. The code runs fine now.

My second question still stands though. I’m I missing a separate plugin?

Could you show me a screenshot of the issue? It could be that Visual Studio isn’t able to find certain definitions that are used in your .cu file.
