Have anyone play Pokemon Prism before? Where you'll choose Larvitar as your starter pokemon. I need some help.

After I beat 2 gym leaders, I cannot advance anymore.I cannot challenge new gym leader of spurge, سپرگا City and تیز پات, laurel City as someone is blocking the door of the gym. In Laural City, I cannot enter the tower as there is someone blocking the door. I had تلاش new places to go, but I cannot found any. Can آپ help me سے طرف کی telling me what should I do get advance?

Thank a lot.
