I'll just go ahead and give you an almost full guide on how to download DracoStory, and I hope it answers your question,if not then please PM me and try to be more specific.
First, Go to your Maplestory folder.
-If you dont know where it is then its
Start > My Computer > Local Disk (C) > Nexon > Maplestory.
But remember that this is the default location of the file and not necessarily where you decided to store it.
When you find the folder, Take ALL of its contents and put them into the recycling bin.
(Or a file seperate from your Maplestory folder)
Next, go to the website and download the Client, Save it into the Maplestory folder instead of Running it.
(also download/save the Vr. 55 Maplestory if that is not already on your computer)
This is the link to download the hacks for this server

If your computer cannot run the file, then go download Winrar @
