CCS/MSP430G2553: Can't upload anything

Tool/software: Code Composer Studio

Hi,

I bought a new MSP430G2 board, and i want to debug my first program.

In CCS i pressing debug, it's compiling and giving me this error:

"Error connecting to the target:

Could not find device (or device not supported)"

The same in Energia:

"the selected serial port tilib: device initialization failed

does not exist or your board is not connected" (Error 57)

I tried to uninstall CCS and install it again.

BTW, the first initial program on the device is no longer working, i connecting the device but the LEDs are not toggeling. It happend after one of my tries to upload my program to the device.

What can i do to fix the problem?

Thank you.
