Ad Delivery Slowed

I'm about ready to give up. I received an email from Google this morning saying that my ad delivery has been slowed down due to low performing keywords and that if this happens two more times I will have to pay $10 CAD to restore my account. But how can I fix what's wrong when my ads aren't even showing yet? Perhaps they are refering to the two ads from campaign #1, but I saw right away that those ads weren't doing well so I deleted them last night. I am so frustrated.
