Energia 0101E0011 and COM Port problems

I tried searching for likely topics, admins feel free to move it to a more suitable Topic

Hello, I hope someone can tell me how to get out of this situation:

Windows 7

Energia 0101E0011

MSP430G2553 

YES I have the drivers installed!

Lately I've been seeing this more and more

I'm flailing away trying to upload my sketch. (Used to work okay)

I make some changes (often), yes it compiles ok but hangs on upload

I use Control-M to upload and open serial monitor (my preferred method but none seem to work now)

The progress is displayed below the actual sketch in Energia.

It will get to Erasing...Programming...Done, 3184 bytes total. 

Done uploading, it tells me BUT

The Upload button in the tool bar at the top stays yellow

eventually I get this message below
