I need some help

Hello dear League community, today I come to you to seek some help . Recently I got that season 4 nostalgia kinda thing, and I wanted to put back the old rift into my league, even tho I am the only one that sees it . So I went into googling to search for it and I found a program called Wooxy, some of you may know about it, and there, a link to the files of the old rift was standing, but when I clicked on it, it said that the page is no longer avaible and I feel kinda upset now :( . Can anyone give me the files on that link or a tutorial how to install the old rift back ? Thanks alot, and btw sorry for my English, it may be bad. Have a nice day !
