Hi, i sent my coins with out a fee and the transaction was never confirmed. Some of my coins returned but 2/3 of them are not back. I read on a forum that if i cancel the transaction they will return. The instructions are posted below. I can navigate here and have backed up my wallet but being new to coins wanted input if this is correct and will work. Thanks in advance for any help.
