Cisco C3759 failed upgrade

I uploaded an image to a 3750 today, changed the boot system variable, reloaded switch. Switch goes through the boot process, outputs loads of @@@@'s as usual, then throws up a "error loading flash", then loads the old iOS bin image.

I checked the md5 of the image from the Cisco site and it does not match what I have on my laptop downloaded images or what is present in the switch when I verify /md5 on the image uploaded.

Any ideas?

I've downloaded the image 3 times and the md5 is not matching what Cisco says it should be
