Don’t know what this program was exactly doing. After installation and registration, couldn’t get into the internet any longer. Deinstallation of the program deleted the Pro version, but the Free version remained. Needed to deinstall this Free version in a second deinstallation action. Internet works now, but the e-mail program does not connect to the server any longer. I’m on Win7 64-bit and strongly recommend to create a restore point manually – before trying this program.
