Sorry, I tried to get a free slot on the hour but failed. I'll try again on the next hour.
I'm guessing if it does work then I'll need to do the same for the the additional transaction i made to either get the funds to the intended destination or back in my wallet.
Aren't either of these addresses from the transaction ID you posted your intended destination?

If your intended destination is elsewhere and you paid a very low fee you might have to use the accelerator again.
editI successfully accelerated your transaction. Viabtc will confirm it in the next block it mines. It hasn't mined one since 15:33 so hopefully it should mine another soon.
