I have been on the dreambox site and this seems to be a official box. I emailed them saturday and gave them the SN number i am now waiting for them to reply but still no joy with box so i still need your help thanks steve

 

Get a real null modem cable and download dreamup and the rest should be simple.

 

thanks for that box running ok now turns out box is fake but i got hold of the seller and he sent me a file by e-mail down loaded dreamup put in the file and its ok now thanks again thought id lost my money steve
