John and I resolved this via email. For those in the viewing audience, John was unknowingly attempting to load a tournament saved with version 3.4 beta 2 using version 3.3. The Tournament Director is backwards compatible, so version 3.4 beta 2 should be able to load tournament files from just about any previous version, but version 3.3 can't load tournament files from a later version, like 3.4 beta 2.
