Hello, I'm new in this forum. I have problems with Malwarebytes Anti-Malware 2.0.1.1004. When I upgraded my OS from Windows 7 Ultimate to Windows 8.1 Pro (without Media Center), mbam simply stopped working. I tried to uninstall and re-install but the installation wizard give me some errors during the installation. When the installation finishes, mbam don't start. Finally, I tried Malwarebytes Anti-Malware 1.7.5.0.1300, and it works perfectly... Why I can't install the newer (and supposedly better) version of mbam but an older version works perfectly????
