Logged in and my account was at lvl 1

Hello! So recently I logged back into my league account after like 9 months or something, I logged in and I assumed it was a weird update and it asked me to choose a summonee name, so I chose one. My account was at lvl one and I had no mastery or skins whatsoever. I came onto the forum to see if my account was still existing and ewisthatabril is the account I can't sign into on the launcher! I know it exists as I'm writing on the forum with my account right now! I think I made two separate accounts. Can someone help me on how to log back in? I typed everything in correctly but I still sign into the wrong one.[sg-ahri-1]
