You need to upgrade your wallet. Wallet's older than v0.11.1 can generate transactions with high S values, which haven't been allowed since October 2015 when v0.11.1 was released.

Bitcoin core nodes will now only accept transactions with low S values. They used to generate and accept transactions with high S values, but that's no longer allowed since the release of core wallet v0.11.1 in October 2015. If his wallet's older than v0.11.1 he needs to upgrade.

Test for LowS signatures before relaying

Make the node require the canonical low-s encoding for ECDSA signatures when relaying or mining. This removes a nuisance malleability vector.
