PVP Kernel

So I recently ran into a problem with my League of Legends that prohibited me from accessing the Legacy Client. So I decided to try and reinstall League of Legends using the Hextech Repair Tool, all that did was delete the already working Alpha Client and replaced it with the broken Legacy Client. So after deleting all League of Legends data off my computer I attempted to re-download it but when downloading it, it automatically downloads the broken and unusable Legacy Client. Please help me solve this issue.
