failed skin shard

Today i got a skin shard and it told me this "You drop in a shard, expecting a magical (and totally scientific) transformation... but instead your shard pops back out. please try restarting your client. if you continue to see this message please try again later; there may be issues with the service." First i tried a few hours later and nothing happened. i tried restarting my client. Does anyone know how to fix this???
