im sorry, but is it safe for me to show transaction id, because it will disclose addresses? it's more than 2 hourse since i've sent coins, so i don't know how long it takes for transaction to fail and coins to return to my wallet, if it is the case.
If you have concerns about showing the transactionid or the address because of the type of transaction you made then I would not post it. Post post them all the time. There really isnt much of an issue of it unless you are doing something illegal or illicit. On the bitcoin wallet I had transactions that ended up in a conflicted status and took 72 hours to resolve. For Litecoin it should only take a few hours.
If after 24 to 48 hours you can always export the private key from your wallet and import it into a desktop wallet and execute it with a -rescan command. That will unfreeze the transaction.
