Can you change your minecraft cracked skin after its already been changed?

I changed my cracked minecraft skin and i tried to change it again and it said that the process was already being used and i couldnt change it again. Can you change it again?

If it's cracked it's likely the game has picked up on your computer (and account) and will try to disable as many features as possible.

Mojang is also not dealing with you personally, many games these days have anti-piracy codes in them.
Example: Game Dev Tycoon adds Pirates so you don't earn money. Pirates do not appear for people who bought the game.

You can't have a skin with a cracked Minecraft client.
