Why can't I get into Pianta Village in Super Mario Sunshine? (GC)?

Okay, so I have 82 stars. All of my worlds done except Pianta Village. I have 20 secret shines in Delphino and I have all 100 coin stars. I also have all of my nozzles. The questions is, when I go into episode 1 of Pianta "Chain Completes Unchained" and I run over to the goop my FLUDD comes up and says "Looks like someone is lacking proper training" what can I do? I have tried so many things! Help please!!!
