Hello 🙂
I think if you have changed your in game name "$lxrd$" and you said your game uninstalled so,
You can try to put your new name "$lxrd$" in samp window nearby Name,
If that doesn't succeeded you can try to put your old name "lazar",
I'm sure one of one of those method will succeed to get back your own account,
If my beliefs did't help you can discuss with patient Moderator,Admin,Community Manager 😀
Thanks.
