Serial Port grayed out

I tried the re=istall - nothing
I tried the access the user to the port - nothing.

"
I am not sure if I have any better advise than SurferTim. The only crazy longshot is open your Arduino IDE, go to File->Preferences then click on path hyperlink to preference.txt file near the bottom of the preferences window. Open and view the preference.txt file and find "serial.debug_rate". Verify that it is set to 9600."

My file was set to 28800.

Setting it back to 9600 fixed the issue!!!!!

Massive celebration!!!!

Thank you.
