Hello there! I just did a trial run of MRU-B on my win-98 machine. After just one run, I got an error message telling me that explorer had errors and would shut down. Now every time I try and start windows Explorer (you know: press the windows icon key with the 'e' key), I get the same message. I have uninstalled MRU Blaster and have re-booted numerous times, yet this problem persists. So now....both 'windows explorer' and 'windows internet explorer' will not run on my machine. I browsed the forum and found no posts that addressed this trouble I'm having and am wondering if such a condition has been reported before. Thanks!
