I started mining this morning and not a single coin, this is really weird, ccminer and cpuminer both say they are mining and found new blocks, etc, but chickenstrips says i have no workers mining!
If you were mining more than 4 hours ago you were mining on the test servers. It depends when your morning was! But if you can post your code maybe we can troubleshoot why you aren't mining

Ive restarted again, still nothing happening, the hashrate seems to change with each block, for example:
[2014-07-06 12:11:49] GPU #0: GeForce GTX 275, 60661 khash/s
[2014-07-06 12:11:54] GPU #0: GeForce GTX 275, 626924 khash/s
My configuration is:
ccminer -a x13 -o stratum+tcp://judge.chickenstrips.net:3888 -u username -p password
I have cpuminer working on another machine with no results either.
