I tried to add introductory media to a project from the properties dialog. I clicked the folder icon in the properties dialog but a second or two after the open dialog opened I got a runtime error and had no choice but to close DVDA. I tried rebooting, etc. and can't figure out a way to successfully open the open dialog.

Next I went back to Vegas 4 and tried to render a different part of the project and the Render As... dialog in Vegas is now doing the same thing. The dialog opens then the runtime error occurs. I had just rendered the intro video a few minutes before this so it WAS working until the crash in DVDA.

Here's the error message from DVDA:

------------------------------------------------------------------------------------------
Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:\Program Files\Sonic Foundry\Vegas 4.0\vegas40.exe

This application has required the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

The error message in Vegas is the same except for the program line which is as follows:

Program: C:\Program Files\Sonic Foundry\DVD Architect 1.0\dvdarch.exe
