Did you check the "set RTS on close" checkbox in the Windows Control Panel for that port, as instructed in the manual?

I am having what may be a similar problem with an APM2.  I have previously used this with Arduplane and and now trying to build a jDrones hexa.  I am running windows 7 (64 bit) and APM Planner 1.1.75 mav 0.9 For some reason I get in an update loop when I start the program but get into it just by clicking no on update).  I have been able (I think) to install the Adrucopter hexa V2.5.4 firmware - the dialog goes fine RX TX lights blink at the appropriate spots etc.  When I then try and connect after completing the update it fails to detect a heartbeat.  If I go to terminal then when I hit return the RX light blinks.  All I get in the terminal window is "I?" every time I hit return.  Tried unchecking reset apm on uSB in planner setup.  I don't have the "set RTS on close" checkbox in the Arduino Mega 2560 cOM port that shows up in windows control panel.

I was able to fix the update loop by downloading the zip file (I had used 64 bit MSI).  I got access to the "set RTS on close" checkbox by changing to the FTDI driver - it had been using Arduino.  The effect of this was I can not communicate with the APM2 at all.  Switching to terminal results in "can't open serial port"

Try rebooting your PC.

Also, did you set the baud rate to 115k?
