i installed cc4 thru 'reallution hub' 8hr ago, and uninstalled 1 hr ago. and i reinstalled now because i'd like to try 'head shot', but cc4 trial expired notify. i am very beginner on cc4, i think it's my mistake check the try button in 'head shot' thinking 'head shot' is individual progrma to the 'cc4' , so after long minutes i realized some missundertood and clicked the cc4 try button and reinstall finished. but trial days expired noticed only. how can i fix this and use trial several days ?
