Hi I am still unable to resolve the problem that I posted a few days ago (CAN NOT OPEN HELP AND SUPPORT), and many thanks to those who responded.I am not sure if I deleted the file for this application by accident, by useing ULTRA WINCLEANER ONE CLIK ,when removing some old games. I did not do a back up, but have done a system restore still no luck. Can I check to see if the relevent files are still there.The PC had service pack 1 instaled I have upgraded to SP 2. But do not have SP2 disc. Can I re download SP 2 on top of the instaled Windows XP ??. Any ideas.
