I am using Win 98 SE OS, and I can't open or use Explorer in any way I can't even browse my computer contents. I have tried every diagnostic test I can think of including Windoctor, Virus Scan, Ad aware, spybot. I reinstalled IE6 twice. I have tried to use the windows update, but it only works if you are using explorer. I am using mozilla in the meantime, but I don't know how to use it to scan my computer contents or how to run any of my control panel programs as they wont work without explorer either. I would really appreciate some help.
