Problems trying to load a program to my new MEGA 2560

Hi all.
I am trying to upload a program to my new MEGA 2560 but it will not let me.
This is a copy of the log.

system wide configuration file is
"c:\ _temp_AstroEQUPloader\avrdude.conf"
using port :\.\com10
using programmer : wiring
overiding baud rate :115200
avrdude: ser_open( ) : cant open device "\.\com10" Access is denied

I should point out this is the log from the program I am trying to upload.
Before this log appears the upload seems to be going fine with all 3 led's flashing away on the MEGA 2560's board.

I am probably doing something really stupid so be gentle with me as I have never used one of these before.
Many thanks

Try to choose a right Board as “Arduino Mega or Arduino ADK” from the Tools menu---->Boards

Hi there
Thank you for you suggestion.
I set all that up when I first plugged it in.
I tested the MEGA with the blink test suggested on the web site and that works fine.
Its just this tried and tested program that wont load.

What code a u using? Try to unplug the usb and then plug it again... sometimes it just stops uploading.

Cheers for that.
I have tried that along with resets and reboots all to no avail.
I did not write this program so no idea what the code is but it is a tried and tested program so I know it should work.
