Techbox I am having the same problem. Since June. I have been emailing tech support and have done the Net Conf Fix twice. Uninstalled, used the removal tool, and reinstalled more times than I can count. I just left it alone for about 10 days and a few days ago it wouldn't even open. Uninstalled yet again, used the removal tool again, and reinstalled again tonight. The data files are version v2014.03.04.09 and when I click to update it crashes or when I reject the update and hit scan it opens the scan page but crashes even without updating. I have had success running it in safe mode without updating. I ran the scan and the rootkit scan as well. Nothing found, but the data files are old. I have run Housecalls from TrendMicro online to be sure there are no viruses. I use MSE as my a/v. I use Web of Trust to safeguard against bad web pages. I do not browse indiscriminately. I do not believe I have any viruses, spyware, pups, or rootkits. AND I have 3 friends that I recommended the purchased version of MBAM who are having this problem as well. 3 of us are on Windows 7 and one on Windows 8. I have screen shots of the program and the errors in EVENT VIEWER. I cannot get this problem fixed. I hope someone helps us.
