How do you sign the failing transactions? Openssl?

Did you make sure you confirming to BIP62: https://github.com/bitcoin/bips/blob/master/bip-0062.mediawiki (strict DER encoding)?

Based on the other thread @Jpja used https://coinb.in to sign the transaction.

My guess is their service still produces high-S values.

Can you try to sign the transaction via CounterWallet or Bitcoin Core, as described here?

@dexX7 I ran a sample address through your site and tried to sign the unsigned transaction with Bitcoin Core 0.12.1 and get this: "error": "Public key is neither compressed or uncompressed"

@unsystemizer: some Counterparty outputs are unfortunally non-redeemdable due to #5939 (comment).

#5939 is from early 2015. Someone did manage to redeem Counterparty multisig outputs in December 2015. https://www.blocktrail.com/BTC/tx/f4e2d186ed56aad9b965370411cece4e65fb8dba33ba04d03295299c273e527f Unless something has changed since, it should be possible. (?)

The DER signature requirement was added by BIP66, which activated in july 2015.
