B737 NG CG autopilot disc problem SOLVED

I think i've figured it out... and forgive me if its already been posted. I ran into that issue with the CG out of limits aircraft unflyable error and autopilot disc. for no "apparent reason". I looked into my aircraft CFG after loading the 37 via the load manager and noticed in some areas commas were replaced with decimals visa-versa. So i changed my regional settings in the control panel back to US config 1,000.00 instead of 1.000,00 and voila. Reload the payload editor and it works!!
