How to release locked coins by CLTV ( BIP65 )

Hey there,

I would like to know how to create the transaction to release locked coins by CLTV. - I have the redeemscript and the private/pubkey of the address. Would love to get some hints as I get only invalid TX when Iam trying to retrieve them.

Kindly regards,
ChekaZ

What commands have been run so far?

Ive redeemed the script with:

addredeemscript

createrawtransaction -> signrawtransaction -> sendrawtransaction thats where the error occurs: TX rejected (-22)

So basicly he doesnt like my created TX, I saw that Peercoin needs a TX-Comment for sending these transactions.
Ive ported coinb.in over to PeerCoin but had no success as the Transaction-build-proccess differs from the Bitcoin based one.
