I have the same problem, the same zipfile etc. Interesting is that after this download fails, the pc that has irprontoedit no longer connects to the internet, can't ping any more nor renew its IP address. It totally messes up the internet connection. It has to be the editorsoftware because before downloading it does find the Ipronto. Reinstalling it doesn't help either, the problem remains. My second pc crashed so I have no way to upload the ICF file to my pc, which I need to do because I have to learn the codes from my samsung STB-C. Is there anyone outthere that has a solution?
