Delete the old zip file, than clear cache if you haven't done it yet, and than redownload the current file.
Could you let me take a look at the .jbeam and the materials.json files? I can help you. --- Post updated --- Also, I made a higher-resolution version of that, since Myushi's template is lower resolution. Enjoy! (PS. The template has not been tested, so if you find any issues with it feel free to report them to me.)
