You have been using the terms "RGB" and "Adobe RGB" and even "Adobe sRGB" interchangeably, so I feel justified in my efforts to clarification.
Please understand that changing your images' colour space DOES NOT affect calibration. There is a problem here, but that is not it.
That's ok, we just need to know how it calibrates with this new system. And yes, sorry I wasn't clear - for troubleshooting purposes, it must be the only monitor connected.
