I've got the latest version of cudaMiner and am using a .bat file to run it with the following flags...
start cudaminer.exe -i 0 -l F24x4 -C 5 -m 0 -d 0 -o stratum+tcp://world.wemineltc.com:80 -O [workername]:[pass]
As far as I can tell none of the commands are incorrect, and I've seen different syntaxes so I'm assuming the flag order doesn't particularly matter. I'm getting a steady 75 khash/s but I don't seem to be getting any hashrate or share updates on WeMineLTC, even after waiting for half an hour.
Also, cudaMiner is the only thing I'm using because as far as I understand it, it has Stratum built it and the '-o stratum+tcp://world.wemineltc.com:80' flag launches it.
Any help is appreciated.
Was mining it for a few months now. I didnt use the latest version but the older version which only supports getwork and run a stratum proxy. Try to downgrade to a lower version. Also, did you see any shares submitted? Try running it without the flag and use a mining proxy.
