Hello I am new to litecoin mining and only have NIVIDIA cards cards they are GTX580's. I have tried to and installed the latest version of cudaminer but it will not work. I tried to fallow a video on youtube but it still will not work. What am I doing wrong?
My system is a Win7 ultimate 64
w/ 3 GTX 580's

When I try to run the x64 app I get the error " the application was unable to start correctly (0xc0000013) Click ok to close the application)

When I run the x86 it will start up it says

1 miner threads started, using 'scrypt' alogorithm
http request failed, Failed to connect to 127.0.0.1:9332; NO
json_rpc_call failed, retry after 15 seconds

It will keep doing this never starting, Also how do I enter info into it? Do I need to have something else installed? Where do I put my wallet info so that I get the coins I mined?

I know this maybe all dumb questions but I have never had a hard time mining btc, so this is all very new since it is not as easy as install enter info and mine.

Thanks for any help in advance,
