Hi! Is there a loading symbol in the top left hand corner of the screen? If yes, it may just be that you still need to download a few game files before continuing; however, if the problem persists, you'll want to contact support@pirate101.com for more assistance.
Well hopefully support can get the needed files from you to ferret out the problem and get you back to having a less stressful game experience. Please let us know how they solve it.
