Make sure your footage layer is selected in the timeline. Make sure that the Camera Tracker plug-in is selected. If you can't see any tracking points then adjust the track point size. If you still can't see any points then move the CTI to a different frame and try again.
If that does not work purge all cache files and re-boot.
If that doesn't work delete your preferences file.
I didn't ignore you, nobody else did either. This is not a live chat room or help desk, it's a user forum staffed by volinteers who have other things to do. Be thankful that you got a reply in a day.
