Do you have this problem with any other HuCards? If so, then the contacts on your console might be dirty. If AeroBlasters is the only game giving you problems, then follow Keranu's suggestion (inspect, and if necessary, clean the contacts on the AB HuCard).
BEFORE you do any cleaning, though, try to "wiggle" (side-to-side) the HuCard in the slot. There IS a little bit of room to play with, but not much.
