Yeah, that happens to me alot

Dunno, the same happened to me, and with alot of other mods too. But only the big mods like heretic. sometimes it happens with small mods too. Sorry, but i have no idea how to fix this.

yep, same for me. sorry but i don't really know how to fix it. go in your files and delete the mod.
i have windows 10 too. maybe its because of that? Anyway, most of the mods i get don't work.
i guess thats just life. things don't always go right. sorry.

Thanks :)

Please help me :(

i tried deleting heretic mod and its folders but its still broken :(
