Help with logic installation anyone?

Hi

since i updated my system to maverick OS X 10.9.5 I have had problems with a few things but mainly logic. Half of the screen is black when i open the program and try to record anything. I called customer support and they said to reinstall the logic cs's- i put in the disk and this is the message i got 'you can't open the application "logic studio.mpkg' because powerpc applications are no longer supported, what does this mean? help me please?
