Yep. I didn't see leofelix's note on success with reinstalling until after I posted. It worked after uninstall, reboot, and then reinstall. I didn't seem to need reboot after that, but I did anyway. My virus protections weren't letting me download the 1.40 installer, so rather than trying to track that all down, I used the 1.36 installer that was still sitting on my computer and made updates from there. It seems to have worked. Thanks for the info and the quick easy fix! tommy t

I'm having the same problems on a Dell Laptop, WindowsXP, TrendMicro. Several months ago I made the adjustments required for Malwarebytes to play nice with TrendMicro. It's been fine. I notice now that at noon (when my daily system updates is scheduled to start), that the rules.ref file was updated, and that a zero length file named mbamservice.exe.mdmp was modified. This would have been when update 2699 was installed. (I added 2700 shortly after.)
