Com ports not recognised

Has anyone had trouble with ucentre and agio having conflict with a com port ? What is happening I have the ardusimple gps on com port 9. The device manager always says com port 9 is working properly but when I get it working in ucentre comport 9 doesn’t work in avionics and vice versa.
.Also does anyone have trouble with ago freezing and the only way to continue is to reboot the tablet.
This is the error that comes up
UDP Client
Send Error: Cannot access a disposed object.
Object name: “System.Net.Sockets.Socket”.

And you do close u-center, before starting Agio, and visa versa? Only one program at a time can use a com port!

Ok thankyou I’ll try that
