Estimated BTC reward remains 0.000 after 16 hours of mining

[MyNameIsCrake]

I started mining yesterday at 55000 khash/s, and 16 hours later, this is what the "My account" page looks like on mining.bitcoin.cz:

I'm running Win7 x64bit using an NVIDIA GTX 275

Any ideas what I should do?

Make sure you are actually mining correctly.

Check URL, username and password. Make sure your miner actually connects to slush's pool.

Where do I enter the URL?
The .conf file in %appdata% only contains username and password, should I enter it there? And if so, how?

Code:

rpcuser=(myname)
rpcpassword=(mypass)

instructions how to set up your miner are right on the front page of slush. just read them.

Wow, somehow I missed entering the url into the bat file that starts the pool mining... I can't even begin to think where I'd pick up the wrong code to put in there.
Anyhow, thanks for you help.

Edit: How long typically until I first see changes on the My Account page? I'm still not sure if it's working

When your miner shows that it has found a share/hash/block/whatever, your account should update pretty fast. On deepbit it's instant IMHO, slush might take a minute (not sure if he's caching the account page).
