Currently I can not flash new programs to the LPC1769.

The part was working good using LPC IDE version 7.8.0.

After I tried to debug using another computer with IDE version 7.3, the problems started.

Now I can not flash or debug anymore.

This is the message I get:

To fix the problem, I tried the following, with no success:
"Board recovery using the ISP pin
If the board's FLASH can no longer be programmed, the image in FLASH may be corrupt. To recover the board, the board must be reset with the ISP (P2.10) pin held low. To do this, attach a jumper between pin J6-51 (P2.10) and J6-1 (GND) and reset the board. "

please help!!!
