When trying to load text twist on my computer it goes to the black screen but does not load.?

it says something about an applet notinted. i have no idea what that means.|||It would help if you told us what OS your working from, your Version number of OS. An noted problems with your computer, and compatibility issues listed on the book. You need to do your own troubleshooting before you just ask a question. I'm guessing your missing a DLL and it sounds like your running a MAC?
