In a great example of the power of this forum, a fellow Premiere user in Ireland gave me some ideas for a workaround. He logged 12 emails to me to try and help me through this problem. In the end, I was able to uninstall Premiere Pro 1.5 and reinstall it (with no help from Adobe) and I can at least open my projects and save them for export, saving the 100+ hours of work invested. CreativeCow is the best!
