I downloaded MBAM (free edition)from CNET downloads and got the following error: PROGRAM-ERROR-UPDATING (12150, 0, WinHttpQueryHeaders). I uninstalled the program and reinstalled it and got the same error. I tried a third time and its still there. The program seems to work but if I click the update tab the error message is still there. Any suggestions?
