A project that I've been working on for a couple of weeks now will not load. I noticed yesterday that when I would scrub the timeline the PPro CS4 would just quit. I restarted, then saved under a different name and was able to continue working. However, today neither of them will load. I also tried creating a new project and importing the unload-able one, but the import process hangs as well. If I try to just import one sequence, I get a the error - 'Adobe Dynamic link has failed'. I tried copying the project (sans media) to another PC with CS4, and again, no load, so it doesn't seem to be either the media, or previews. I tried opening the 'auto-saved' versions, and none of them will. I tried opening other projects, and they load completely with no problems. I've even tried the XML Wrench route, but the project file checks out fine.
Looks like a total re-edit, unless anyone has any other pearls of wisdom.

I'd check this out closely first, especially considering all that you have done with the problem Project.
Good luck,
