I'm not sure if it's the right place to post it but since time passes and I don't want items to vanish or not be on sales anymore...

I cannot purchase Gems at all. When I want to log in the shop(https://archive.smitegame.com/store/), I got an error message: Login Error Incorrect username or password

I checked many times and I can log in game or here or even on myhirez website...but I cannot log on the Gem store to purchase Gems. I've been told that I'm not the only one having this problem. Support hasn't answered me yet and I'd like to get my items before it's too late. Can anyone help me?
