I think so. Don't worry, I just don't like downloading unknown files, so I didn't download that DLL... You can experiment with another castle, not the Elven one, but I was busy and haven't experimented yet.

Well, I understand that in general, but if you don't trust this link, you can Google the "soapy textures bug" in Heroes and look for other links.

The developers of 5.5 posted this fix on moddb, so I think the links there are definitely safe.

And most likely, this is already fixed in the GOG version.
