The DropBox links are a bit of an issue, I'll see if we can get them changed to something like Mediafire or another platform.
The links are not working, but you can feel free to look for other maps like this map. Has your question been answered? If so, please reply within a few days
SkyBlock2.1 Hopefully the links are updated soon but for now this is the download from this site I reuploaded for everyone.
