Did you set up the proxy properly following the instructions? How did you start the proxy? Which version of Windows XP is installed in your computer? What is the state of updates? No detailed information, no help is possible! And I wrote a lot before, but no statements from you what I suggested: OnePiece Windows XP Post-SP3 UpdatePack, Linux Q4OS (Trinity Desktop) and so on. Truth be told, not much fun helping you!
