AppInventorForAndroidCodeblocks problems running it.

I been having problem with this part of the process to start with ALive Complete, and that is the block editor I hit the button to download but i only get this to screens

The problem is that i have try to find information in how to fix it and i can not find nothing to help me with this problem i have try all day long trying to get that part runing.I cam to this software because of the option that is so call more easy to use then MIT APP INVENTOR well from the videos i have seen it is but to set up in your pc is a pain i came to the idea to use this one because they give you the chance to make bigger apps but by the looks of it if i can find help i will only go back to MIT.
