what the problem that you found in previous version ?
If you run with --benchmark -D you will see the problem. I have many copies of my sourcecode, and since it was a long time since the spreadcoin update I changed the wrong source three wich contained a bug in the hash somwehere. I managed to locate the correct spreadminer 10 fixed 3 source, and apply the latest improvements there.
--benchmark -D now give you a correct hash output, so the new version should work. My testrig is mining but haven't found a block yet. (32MHASH) 30 minutes of mining
