In one and a half hour I made only this ... but why does it show payment from only 2 blocks ?
My .bat is cudaminer.exe -o stratum+tcp://stratum.netcodepool.org:4093 -O [my id].[my worker]:[worker pw]
I also get a lot of Disconnecting stratum connection...
Stratum connection interrupted
Yes you are mining. Your pool found 2 blocks since you've been mining and you were paid your share of those blocks.
Seeing "Stratum found a new block" is your miner communicating with the network, and the network said "Someone found the last block, start hashing for the next one." it does not mean you found a block.
Disconnects are from you or your pool. You should test a different pool or two and see how it goes.
