So, I'm trying to open another person's track, and I'm pretty sure you press remix to do that. The only problem is, every time I try to load it to see how they set up the notes that they did (because I don't know how to do what they did), it either says "Connection Failure" or it loads about halfway and then gives me a blank grey screen. I have the latest version of Adobe Flash Player, I have an activated account, is there something else I need to do?
