I just "upgrade" my laptop to windows 7 (32 bits) and put Energia folder in the root (C:\Energia) then i have installed MSP430 drivers and... Again, just the same error when i click on the "Upload" button.
I'm using the "UARL" Port which is the COM5 in my case and the MSP4305529@25MHz LP. The Baud rate for this port i'm using is 9600.
