Help me T-T

Okay so idk if its my heckin computer or what but when I try to open league the lol logo opens and sits there. It freezes and doesnt open the login screen. I've tried EVERY option to deleting files to reinstalling to opening my firewall to see if its blocking league from running,. So now i've decided to keep it running until the day it opens the login screen. Unless someone can help me. This happened pretty recently over the past couple of days but today no matter what i try nothing works ;( Hope someone can help [sg-janna] UPDATE: So my friend and I searched endlessly to work this out and I am SO glad to find out the solution. For anyone who is having the same problem I want to share the solution with you guys! [slayer-pantheon-thumbs] Delete your Replays folder, restart your computer and relauch the client before attemping the fix below. It does not require a reinstallation of the game or deleting hidden files and is a solution.

I can confirm that this solves the issue of the client not opening and being stuck indefinitely on the League of Legends logo. Today's 8.21 patch is the culprit.

All credit goes to Cornboss. I am just regurgitating the steps I did.

Solution:

1. Uninstall League of Legends.
2. Navigate to your AppData folder (e.g. C:\Users[username]\AppData). This is normally a hidden folder so it is best to type out the address into File Explorer. Additionally you can type %appdata% into File Explorer and click Enter. It will take you to C:\Users[username]\AppData\Roaming. From here click on AppData in the path field to get to the main folder.
3. Delete any folders associated with Riot Games or League of Legends in the folders Local, LocalLow and Roaming.
4. Navigate to your Documents folder then League of Legends where your Replays are stored and delete that folder. It is beneficial to delete this folder occasionally, since old replays do not work after patches and it frees up space on your disk drive. (I did not touch my Highlights folder.)
5. Reinstall League of Legends.

The client will now open and patch successfully.
