DVD Architect 5.2 Render Freeze at 84% and 98%

Hey gang! So... worked through all those Sony Vegas Pro 11 blues and finally created a DVD with menus in DVD Arch 5.2 (Build 133). When I preview it I am delighted with everything. It is 53 minutes long and tops out at 4.2GB so that isn't why it freezes. I've made 18 prior projects successfully and thought I had it down pat. My DVD Arch project freezes when rendering at either 84% or 98%, and the ticker just keeps on accounting for the elapsed time like it wants to finish but no cigar.

I am a home editor doing family vaca stuff:

HP Pavalion a6628f PC
Vista 64, duel core, 4gb RAM.
Modest Adeon Vid card but better than the nVidia that came stock.

As you can see I am adequately armed even with a 3 year old computer. I used SONY Movie Studio 9 Platinum for years with zero headache, but this Pro version (bug wise) has been a challenge.

Does anyone have a suggestion how I can render my final DVD with success? (no freezing). I just want to render, burn, and move on to new pastures. Thanks!
