Ajuda com cudaminer - Help with cudaMiner

Hi, I’m starting and I have a problem while I try to start the cudaminer.
I have nVidia GeForce 740M and I set up my pool at https://www.litecoinpool.org/1
My .bat: cudaminer.exe -o stratum + tcp: // linkDaPool -o acc: pass

It’s in the cudaminer folder. When I start my worker, I have a following message:

C: \ cudaminer \ Cudaminer x64> cudaminer.exe -o stratum + tcp: // linkDaPool -o xxx: xxx

Press any key to continue. . .

and do not start mining

I have already tried with the parameterized worker this way:

cudaminer --algo = script --url = stratum + tcp: //us.litecoinpool.org: 3333 --userpass = acc: pass

and it’s the same

Does anyone know what’s happend?
