star wars : empire at war mission 8 empire help

[viruz777]

hey seniors!
i'm currently playing mission 8 for the empire - the traitorous moff in empire at war.i'm stuck at that mission mainly because after all the talking and i'm required to send a fleet to confront moff tarkin's fleet at azterri. But once i've sent my fleet,it instantly says either i've won the battle or lost it, depending on the size of my fleet when actually after reading gamespot's game guide, i'm suppose to initiate a space battle and battle it out but i dont even get a chance to! what more when i've won, i send a large ground army to azterri and manage conquering it instantly or losing the battle...STILL NO CHANGE!! it's frustrating really..can anybody help me please?
