[Closed] 3ds max sdk debug problem

Hi, I am a newbie in 3ds max sdk. I have tried to debug a plug-in with VS2008 SP1 and 3ds max 2010 sdk under windows vista 64bit. When I execute 3dsmax (run from visual studio) I get the error: “Protection Error: Debugger detected – please close it and restart!” Any idea? Thanks in advance. Joel.
