The automatic consistency checks of the dataserver noticed that the new version references the Python file WalkingMaze_BookGUI, which is however not shipped with the age. The file is called WalkingMazeBookGUI instead. I could fix that in the prp file, but it would probably be better if you did that in the blend file.
Your age does not have an age descriptor, so I created one for it. See
http://www.guildofwriters.org/wiki/Offl ... umentation for a description of those, and
http://www.guildofwriters.org/wiki/UAM# ... ge_via_UAM for how to create an age package with the folder structure required by UAM.
Packaging the age with such a structure is not a requirement to get it on UAM, it just makes my life easier since I do not have to sort all the files in their folders myself. You can download the last version of walking Maze from
http://www.the-deep-island.de/uru-ages/ ... 2-03-27.7z to see how it looks like with all the files in their place and an age descriptor added.
