Due to continual spamming, forum registrations are now by Invitation Only. Hopefully this will be only a temporary measure to combat spammers.
If you want an invitation contact forumapplication @ camstudio . org
Sorry for the inconvenience.
Mozilla is actively blocking hook.dll because some other poorly written program uses that name for its dll. CamStudio should name it something else. Also, it should attempt to load it once and not repeatedly.
