Thanks Steve - Uninstalled and reinstalled several times. Also re-downloaded a fresh copy of the installer in case something was corrupted during the download, although I'd expect a CRC error if that was the case. Yeah 'feels' like a .NET constructor that isn't being initialized properly that's throwing the exception. But it's odd that other folks are rendering fine w/Pro v11? Leads me to believe there's a strange configuration issue on this PC. It's Win7 Pro SP-1. v01e always ran/rendered fine.
Also installed v11 build 424 (32-bit) and the error message is identical?
Put a support request in to Sony the other day, but nothing yet. I had complete confidence in Vegas based on past experience, so I let v11 convert the project without making a copy. :/ Might have to fall back to v10e and redo the project from scratch.
Please let me know if you have any ideas cause I'm drawing a blank.
Thanks again,
بعد البحث فى اعماق البحار احب اقولك اعمل REINSTALL للبرنامج لو ظهرتلك تانى حمل البرنامج من جديد
