Guide on adding a new model, animation, and creature to HoMMV

Ugh, everything always goes wrong somehow (other files work right away). On page 20, I posted a link to the program "GR2Tool_by_Distraught_granny211_v13.exe". Try dragging the file onto "GR2Tool_by_Distraught_granny211_v13.exe" -> enter 1 3 4, press Enter -> a copy of the file with the suffix "_new.gr2" will appear (try opening it in the "Noesis" program, and if that doesn't work, replace the first 16 bits in the file header using a HEX editor, as described below). Open the resulting file with a HEX editor and change the first 16 bits in the file header from "29DE6CC0BAA4532B25F5B7A5F666E2EE" to "B867B0CAF86DB10F84728C7E5E19001E" and save the result. Now the resulting file is ready to use (I managed to open the 268 KB file, just like in your screenshot, which wouldn't open right away).
