hey guys , i need a lit bit of help

i sometime make graphics/logo for people , usually its for my own sites so i use the png but when i am making for others they ask for psd and Ai files usually. Well when i save the files as Ai from fireworks it comes as it is but when i save as Psd and open with Photoshop the affects arent same as it was in Fireworks

how can that be fixed , any plugins or something ?

oh i am using CS4
