No debug messages

I get this exception on one computer.
There are no debug messages bit the code works. I can set break points and see the variables.


The same code works(debug messages are ok) from another computer.
I tried reinstalling GHI SDK with same result

‘Microsoft.SPOT.Debugger.CorDebug.dll’ (Managed): Loaded 'C:\Program Files (x86)\GHI Electronics\GHI NETMF v4.1 SDK\Assemblies\le\GHIElectronics.NETMF.Hardware.ChipworkX.dll’
The thread ‘’ (0x2) has exited with code 0 (0x0).
A first chance exception of type ‘System.InvalidOperationException’ occurred in GHIElectronics.NETMF.Hardware.dll

You need to step in code to see what line is giving you the exception and why. Maybe share that code here as well.

Does the firmware on the board match the GHI SDK version?
