Looking at that error message, you should have no problem at all with your heRO installation. It claims one texture from the Basic Interface failed to install correctly, which really doesn't mean anything. Basic Interface textures exist both in data.grf and sdata.grf, and RO should simply hop to the next source if it can't find the first one. I'm not exactly sure which texture that is, I don't recognize the name, but your installation should work without problems. If it doesn't, there might be something else that's going on as well.
