I got it fixed…
This worked for me- below:

I trashed the Motion application (even though it was updated to 3.0.2).
I reinstalled just the Final Cut Studio files using the Final Cut Studio install disks (didn’t install any of the extra stuff)
went to Software update, which offered to update both the Pro Applications Update AND Motion 3.0.2. This time, I ONLY had it install the Pro Applications Update, NOT Motion.
After it installed, I opened FCP 6.0.3, still got the black screen with the Master Templates.
I went back to Software Update and THEN installed the Motion 3.0.2 update.
rebooted and opened FCP, and the Templates were finally working again.

Thanks Peter.

I am running FCP 6.0.4. Everything is up to date as I stated.

I repaired permissions and trashed the preferences. Still the same problems.

But thanks for the advice. If you have any further thoughts please let me know.
