If your knocking resistors off during install I would send it out. Smd resistors are super easy to install if you know what your doing. You could get a resistor from RadioShack and tack it on but then you run the risk of every little nudge threatening to lift a pad.
Send it to someone in the us who has experience this is a problem plaguing people currently. I personally have fixed quite a number of these with pads remove yours would be a piece of cake to fix since they are still attached.
Im willing to fix if you want. It would be 20 bucks for such a simple job. If you knocked the resistor off I'd have someone install the cr for you. I would install that points wire for you so there is no chance of failure due to repeated actions.
