lg env memory reset?

[flightattendantman]

on my lg env (verizon)-- whenever i type on the keypad for a text- whenever I push the " ( " button (SYM 9), it goes to an autocomplete word. also, whenever i push the " * " button (SYM 8) it inserts a phone number after the *

what can i do to make this stop other than to stop using those symbols? thanks
