Free version limitations?

hi im new using flash EFF, i just downloaded it today. but i was kind of wondering. what are its limitations. im using the free version. and i was trying to make some cool buttons but somehow i only can get just two of them to appear. am i doing something wrong or that is just part of the free version limitations? thanks :)

You can have more than two effects. Please note that you need a different component for each animation. The only limitation of FlashEff Free is that you can use only one preset for each pattern

Owh i see. thanks :)
