have you tried 'repairwallet' from the console?

The coin will be delisted from trex ?

Do you have any coins in your wallet? If not then do the below and let me know if you have any other questions.

1. Follow the below only if you have problems syncing and do not have any coins in your wallet.
2. Delete everything KTK...ie wallet, downloads, all folders, etc. in Roaming and anywhere else you have anything KTK related.
3. Do a computer search for KTK and delete any files that come up (hopefully none, but you'd be surprised).
4. Download wallet from OP for your OS.
5. Open wallet. IF any errors occur, close it and reopen.
6. Once wallet opens, close it down.
7. Go to OP and get the config file for nodes.
8. Make config file (if you don't know how to do this let me know and I'll make one for you and then sent it to you)
9. Place config file in KTK roaming file (same folder as all other files)
10. Open wallet back up and let sync. Might take awhile. It is a memory hog so close all other programs for faster downloading.

IF this does not work for you then PM me and I will get you through it another way.

AGAIN THIS IS ONLY IF YOU HAVE NO COINS IN YOUR WALLET. IF YOU DO THIS AND HAVE COINS IN YOUR WALLET THEY WILL BE GONE FOREVER

i already tried all above mentions things, but still nothing happen so im tired and do not wants to  sync any more,,  good bye ktk....

that seems to be normal fuding practice in BTT forum. Seen a lot of that in XBoT topic, where Dev practically gave up on posting at all being overflown by fuders.
The only option is to ignore such posts and report them to be deleted.

You were stuck at block 271k, I updated the .dat file (after seeing your post) to 576k so it wouldn't take much to sync!

awesome 

yes, that is indeed a great news. KTK deserves more attention from broader public.
Thanks Dev for the hard work!
