(Client) Game loads for a seccond when opened and closes shortly after.

This is the seccond time this has happened, once yesterday. I used the hextech repair tool to try and solve it though it couldn't find the client.exe in the default place and I don't know why. I looked in the default place and only found a LoL file with an empty replays folder. I did some more looking on my PC and found what i think are the files needed for lol. I tried opening the client up from there and still the same problem happened. I'm performing another clean uninstall to fix it though I feel it will happen again.

Steps to reproduce. 1, Try opening LoL as admin or not admin

Expected result: Loading up the login screen Actual result: 2 - 3 secconds of loading followed by it closing without any notification.

I'll keep the files collected by the repair tool to help out though i don't know how to submit them.
