Not sure if GPU mining is working

JungleOnion

Hello, I am using MacMiner version 1.5.42 (1542) and I am trying to mine scrypt coins with my gpu but when I set the pool and the configuration to start mining I get this message:
The primary pool is set to stratum+tcp://wdc.coinmine.pl:9090 and the user is set to jungle
and then:
Your miner was restarted automatically after a sudden stop at 20:08:11.
And I'm getting this message.
