Hi, pbust. I followed those steps to the letter yesterday before posting here. Just now, I went to Program Files (x86)\Malwarebytes Anti-Exploit and double-clicked on the mbae application. For the first time in two days, IT RAN!!! How long this will continue to work, I don't know, but according to your mbae-test program, I'm protected again. Wow. I hope this keeps working, but I also wish I knew what happened and what to do if it happens again. Anyway, I'll keep you posted on whether it works correctly the next time I boot up - and whether I have to manually execute it. Thanks. Harvey
