The newpiskel sprite on the Demo Layout is corrupt, but the project still loaded for me.

So just add a new frame to the piskel sprite in the Image Editor, add any graphic, then delete the first corrupt frame.

It all appears to work correctly afterwards.

Wow, thanks a lot, im really new to this and have no clue what im doing.

Thanks!
