Alrighty, when IRC won't log you into the server, there could be several reasons. I need to know the error message to make sure, but here are some possible reasons:
1) Your IRC client has passed its trial period (very few really matter with this, but it's a possibility)
2) The server is full.
3) Your settings may have changed.
4) You don't have it on auto-connect (in which case you have to click the connect button)
5) You did not put the port to 6667 (happens a lot)
These are only a very few problems. If you post the error message and your IRC client, I should be able to decipher it better for you. If you'd rather try yourself, you can check out the Help section of your client. Get back to me either way.
