Can't login anymore

[minaga]

Hey guys I recently changed my minecraft username (microsoft account), and haven't been able to login into the server. If i try to register my new name, it says its already been registered. When I tried to login with my old password, it says its incorrect. I tried resetting it but it says I need to link my email and when I try to do that, it says my account needs to be authenticated.
Could someone please help me, I'm so lost. Thanks.

Since Pika is a cracked server, username changes are NOT supported. Since you already changed your username, your only options are to use a cracked launcher (tlauncher), or change your premium username back to the original one. Changing your username on Pika will simply start you on a fresh account, and stats/ranks/etc will not transfer.
