I was sure it was a power issue for me... My battery had enough power to only allow reset of the cpu, but not loading or erasing Flash.... It seemed to make sense , since the msp430 draws more current for programing and erasing...and after i changed the battery, everything went back to normal... Your scenerio might be a little different, i am not too sure.. Hope some one on the mailing list can help... I am curiuos to find out what is the cuase of your problem....
