Thanks, but it didn't help

I just tried this:
ccminer -o qcn.pool.minergate.com:5557 -u my_email_at_gmail.com -p x
and program starts allocating threads, and then crashes..

...I also tried - but I think we have to wait for stratum support at minergate.
ccminer -a cryptonight --no-stratum -o
http://duck.pool.minergate.com:5562 -u
your@gmail.com -p x
with this commandline I just get:
JSON-RPC call failed: {
"code": -16,
"message": "Slightly stale share"
}
submit_upstream_work json_rpc_call failed
...retry after 30 seconds
