So i just got a brand new macbook pro 2.4 i5 4 GB ram and im running Lion on it.

Got Logic Pro off the apple website and downloaded everything was smooth, until i opened it.

With no midi hardware or audio interfaces attached it kept giving me the Midi Timeout Screen telling me to update all audio drivers and midi drivers which i have no clue how to do (total noob) please enlighten me as to what i should do, very frustrating...thanks in advance
