Eurovox 100 sl "downloading is failed"

I follow the flashing guide for my box and everything goes well, it downloads for 90 seconds and then I get the "downloading is failed" message. Just to be sure, I connected it up and it says updating codes, so it hasn't flashed. I do have the right cable as I flashed the box once before and it was working ok.
I am using a usb-serial connector and windows XP
Any ideas please?
Thanks, Mike

 

Sorry the box is the Eurovox EX1000SL

 

Is it the correct cable there are two and to the naked eye they are the same, one is a straight through serila (NO GOOD) the correct one is a (NULL MODEM) lead.

Yes, it is the correct cable, it is the same one I used when I first got my box in October and it flashed ok then.

Is there a problem with using a usb - serial converter?

 

There is quite a bit actually, but you had better go to here and read down the page to assigning the correct COMM port. >>>>>>>

Have now solved the problem and flashed the box, the solution?
I bought a different usb-serial converter and it worked first time.

Thanks to those that tried to help out, much appreciated. The converter I got that worked is made by 'Prolific' and is sold by new link products.
