Total newbie help please

Im very new to flight sims and addons so please be gentle but I cant even get anything going on this, and not being a pilot or pro-simmer Im finding the documentation a bit confusing.Here is where Im up to:Tune the com radio to 135.7 and make Initial Contact with the clearance controller."Kansas City Approach cessna one one five one delta"Reply - cessna five one delta clearance go aheadYou require departure instructions to depart north to Eppley at five thousand feet (see Departure Instructions Request)."cessna one one five one delta will depart north for Eppley at six thousand"Reply - cessna five one delta clearance go ahead"International Clearance cessna one one five one delta will depart north for Eppley at five thousand"Reply - cessna five one delta clearance go ahead I dont seem to get to the "International Clearance - cessna one one five one delta cleared to enter bravo airspace after departure fly heading zero eight five climb and maintain three thousand squawk three zero one three" reply, everytime I repeat the "International Clearance cessna one one five one delta will depart north for Eppley at five thousand" she replies cessna five one delta clearance go ahead.Is this a voice setup problem or am I too dumb and cant read the docs properly?
