Christopher. Do you have CT installed? If so, you may wish to try uninstalling CT first then, try relaunching Sonar. Then, reinstall CT after a successful Sonar launch.

I have a pc with sonar 7 and although it worked yesterday, today when I launched it, it came up with a message "A Controller/Surface DLL is not installed" and the message will not disappear. Enter, Escape do not make it disappear, so I basically have to reboot. I have tried to do the control alt delete and force sonar to quit but that does not work either. My next idea was to install sonar 8.5 on the same pc. I did that and the same message came up. Does anyone have any ideas on this? Thanks,Christopher PLEASE READ THIS FOOTER AT LEAST ONCE!
