rpandassociates, POS (staking) did not even start for BTX until block 2880 which was only 173 blocks ago (within the last 12 hours or so).  Before that, the coin was only POW (Proof of Work).

Yesterday in this topic (a few pages back), placebo provided a new secondary node that should be used along with the primary node to ensure your wallet is on the correct blockchain:

BitcoinTX.conf
addnode=107.170.57.24
addnode=178.62.235.171

Check the previous pages for instructions to clear out everything but your wallet.dat and add this file.  Restart your wallet and allow it to catch up.  You are now on the correct block chain but since your wallet retains those old entries, they will probably still show as conflicted.

Now, log into C-CEX and see if your account there has those coins.  C-CEX cancelled any withdrawals sent to the incorrect blockchain and placed those coins back into everyone's wallets.  If there, you can simply withdraw them again.

Now, make sure your wallet is "unlocked for staking" if you have encrypted it and sit back and wait.  Your coins should start staking and you'll see the indicator at bottom right show that and hovering over it will display your stake weight.  You won't earn stakes with every block but your stakes when earned should average 20% per year.

Hope this helps.
