Please confirm that you've gone to Windows Update and manually downloaded even the non-critical updates, that you've downloaded the latest version of Quicktime and that you've followed all of the suggestions above.

You may need to contact Adobe Tech Support. Something is going on with your system that's too deep for us to troubleshoot on this forum.

Those "boxes" indicate a font, that PrE could not display. All Adobe programs are very, very sensitive to fonts, and Titler is probably the most sensitive.

What font was chosen?

Good luck,

Unfortunately, I have never used Instant Movie. However, I will bet that others will be able to give you advice using it.

Good luck,

I just did some experiemnts with Instant Movie.

For your Title, in Expert Mode, you would first Select your Instant Movie Clip (everything appears as one big Clip now). Rt-click on it, and choose Break Apart. That will change that one big Clip into all of the various elements, used by Instant Movie. There will likely be several Video Tracks, with Clips on them. You might have to scroll up/down to find the Titles. Just hover your Cursor over the various Clips near the beginning of the Timeline, until you find the Title. Dbl-click on that, to open it in PrE's Titler. There, you will be able to Select the Objects in that Title, like the main Text Object. You can Select that with either the Selection Tool (the "arrow"), or with the Text Tool (the "T"). Once you have the desired Text Object (if there is more than one), you will see the Font selection drop-down, under the Text Tab in the panel to the right in Titler. What font is shown? If you change that font, does your Title now display properly? As you will likely have two Titles, one with the Instant Movie's chosen name, and one for the end-credits. I would explore both, as they probably used the same font, when created.

Good luck, and hope that helps,

Hunt

PS - thanks for your question, as it got me thinking and experimenting, so I learned something there.
