the a swer to your first question is yes, i followed the steps EXACTLY as they are listed on the wiki page
for your comment, well, you see, i have once compiled an older version, i think it was 80.5 or something like that, and it worked fine except the diamond would melt, and i couldnt figure out why, so i redid the entire thing, downloaded the newer files and all that, and the first time i went to build, it seemed like it would work, then i got that fatal error and it didnt even open tpt like it had for the older version
