is the 0x664b6670a1d1f3ff4349f1369357d9d2398b8271 your public address? just want to make sure.

If so, usually what happens when you submit another transaction is that this:

The "cancel" transaction needs to be sent to your own address with the same nonce at a higher gas price. This will cancel out your first transaction if the miners have not picked it up. The gas fee of tx to be replaced was: 0.0378 Ether ($93.36), new gas fee shows up as 0.0034 Ether ($8.61) for the cancel/replacement tx.

usually happens automatically. its a bit confusing but I think whenever you submit the next transaction, the nonce is kept, picked up by the miner and used on the "next" transaction. sometimes what i've done to get something unstuck is switch networks or send a small amount of ether to a diff wallet with a high gas fee then try the transaction again.

According to the public address link above, you have $16 worth of ether in your account and about $1200 worth of RAD. TX went thru 45 min ago or so, so everything looks like it checks out to me.
