But just in case it persist beyond 24hrs you can ask the sender to resend the transaction again but this time with a more considerable high fee cause atimes these delay could be due to the transaction fee amount.
Where did you get the 24 hours from? Why not 12 hours or 48 hours?
The transaction has been already confirmed and it doesn't matter how much fee has been paid for that.
You can go through this thread below for more help.
achow101's guide can't help OP. As already mentioned by OmegaStarScream, the tranaction in question is not a bitcoin transaction.
