I'm giving Bittrex additional 2 hours to disable their wallet before I proceed with the hard fork
Hard fork? what am i supposed to do exactly so i dont lose my coins! please advise
You just need to install the new wallet.
But if i dont have access the computer that the coins are in for the next 24hours, what happens?
Doesn't matter, next time when you sync make sure you use the new wallet, just to be on the safe side backup your "wallet.dat".
I have never encountered this before, please explain it to me step by step in explicit detail, much appreciated!
