Walkthroughs for custom maps.

Does anyone have any thoughts on my question? Maybe this plugin only works with the English version of SoD (and I have the "Complete Collection" from Buku)?

I have the Russian version of the complete collection. Everything works; I can't imagine what the problem might be.

But I also have the HD mod and SoD_SP in versions that aren't the latest; maybe that's the issue.
