I own TrackX and SliceX, which I use on FCP 10.2.2 running on OS X 10.5.5.
I installed the trial version of DriveX, and the tracking seems to work well, but the 3D text just sits in the center of the screen. It doesn't seem to "attach" to the tracking data. I believe I've tried everything but all of the plugins in the suite seen to behave the same way. Am I missing something obvious? SliceX and TrackX are still working perfectly.
can you please check if it works in a new project?
Also, can you please check the system log for error messages when you try to track in DriveX? You can find the system log when you open the Console application and choose „All Messages" from the list. Then please search for messages from FCP X and from VTwinFx.
