Terrible Freeze

One major glitch that I know happens for me at least - every time I reach the scene where Hagrid and the students walk into the Great Hall in Year One, the game freezes and I lose all my progress in the save. Hoping you can fix this bug, because it keeps me limited to playing only the Leaky Cauldron and Diagon Alley areas. Almost all of the gameplay is denied of me due to this glitch.
