arduino mini does not upload program

I have an arduino uno to which i succeeded to upload one of the examples (reading analog pin 0)
i purchased an arduino mini and a usb to serial converter.
i fail to upload the above program although i:

followed all the steps in the Arduino getting started guide
added the inf file to update the usbserial driver
reset the board manually or with the reset connections shown on the diagram of the guide

I use windows xp
please help

..if noting is broken.. this shall work out
Give more details: exactly what...How connected ?

the connections are taken from the guide (see photo)

Yeah.. thats what I've done, except from the reset parts..(i use the 'manual' reset switch).
..sure the bootloader is present? (else I got no idea... (sorry)
