I don't think the problem is with the USB to rs232.

So the pre built hex files load just fine.

Your hex files are bad.  check for the differences between the prebuilt and 
the ones you build.
http://www.cs.net/lucid/intel.htm has a nice page expaining the fields in the 
hex file. 
http://www.keil.com/support/docs/1584.htm is a good one too.

Bad address?   Checksum wrong?
