Migration from cracked to premium acc.

[IMgamingOP]

I am an old bedwars player on this server and till now I had been playing with a cracked account (IGN: IMgamingOP), I recently purchased minecraft official account and used the same ign so I can continue with the progress I did on my cracked one.
The Issue: My real MC skin is now appearing at some places even after using the </premium> command, I think this might be due to my old cached data, please if possible fix that

I cannot understand what you mean, is it that you cannot see your skin?

Anyways this might be a cache issue on YOUR end, delete all the files in USER_FOLDER\.lunarclient\cache or delete your whole .minecraft folder

Yeah I guess it's the issue with Cache only
I don't actually use Lunar Client
So after deleting the .minecraft folder, what should I do
