It sound to me like you are having a problem with your cross wind. Make sure you take the opportunity to practice landings at airports where the winds aren't typically down the center line. This will quickly force you to develop proper rudder skills. Best time to do this is during the middle of the day when the winds are typically stronger.
In this instance, the ball is not your friend, don't attempt to use it during the landing phase of flight.
As mentioned before, the x-wind factor will constantly change through out the landing phase, which will call for constant rudder correction on your part.

GAI incidentally is where I perfected my x-wind landings, though it was during the windier months.
If you're flexible and can grab an instructor on short notice when the winds pick up, you'll tame them pretty quickly.
Good luck!
