My Early Access Key to Path of Exile 2 Disappeared! 300+ Hours Played, Now It Says "Buy a Key"?

Hey everyone, I’ve already spent over 300 hours in Path of Exile 2, and I have an 82 Monk plus a Mercenary with gear worth around 200 Divines. I bought my Early Access key back in December and have been playing without issues—until today. Suddenly, the game tells me I need to purchase another Early Access key to continue. This makes no sense!

What’s even more confusing is that I didn’t receive any email on my account or any official notification about a ban or suspension—nothing from the game’s website or in my personal inbox. My old key just seems to have vanished, and now I’m locked out of the game, despite my characters still existing. Has anyone else experienced this? Any ideas on what’s going on or how to fix it?
