I have a transaction that has ended up stuck in Unconfirmed Transaction. Looks like I made a mistake and the fee was too low. I'm afraid that this won't ever get committed. How do I cancel and resend the transaction with Armory? Is doing this safe? The transaction has been stuck for 20 hours or so. It was a simple transfer from BTC to LTC

Here is the transaction: https://blockchain.info/tx/af4fb858b6ae6226b055f7c7304b50771fbaa8875afdb1c2d3dd90bbfe3481d8

I've read how to zapwallettxes here: https://bitcoin.stackexchange.com/questions/9046/why-is-my-transaction-not-getting-confirmed-and-what-can-i-do-about-it
but I'm not sure if that will cause other issues with my wallet and address

Please, if you can, provide guidance here.

thanks,
