blI have a fgdb which I converted to V10 from 9.3. I am able to open the database, but the tables all return the code -2147024809 (Invalid function arguments) when I try to open them. I was able to open them with one of the earlier beta versions. I can list all of the tables, just not open them. Of course, the tables work fine in ArcMap. Is this possibly a XML issue. I see that this code is returned when creating a table with non-complient XML.
