I just installed VisualMicro today, mainly to use the debugging features. I created a new project and it compiles and uploads to the board perfectly.

However, when I add breakpoints and rebuild, a window appears that says: "unable to start debugging. unable to establish a connection to gdb"

In the debug window, I get the following information: 
"\arduino\tools\openocd\0.9.0-arduino6-static\bin/openocd.exe" exited with code 1 (0x1)." 

I confirmed that openocd.exe does exist in that directory ,but beyond that I don't know what to do to get the debugger working.
