I installed the latest version 4.8.289 And instantly on start-up (of the program, not windows) it freezes the system, everything becomes unresponsive. Ctrl+Alt+Del doesn't work menu system doesn't nothing. I have to hard power down and then back up.
I have a brand new Toshiba Satellite L850D -12Q running windows 8 64.
I thought it might of been a one off so I uninstalled and re-installed the program and it froze again. No errors just mass stoppage.
