Lion Update Problems

So, i hear that the os x lion got an update about the iCloud and another OS improvements,

so, i search in the mr.google's engine and found a few Combo Updates, but the size was only like

300 MB or somethin' , then i installed it, it told me to restart, and when i heading to system preferences,

it shows NO iCloud !!!... so, i wait for the apple to released it on the support section, then i downloaded it for

like 819 MB, then i try to install some, but they said " This Volume does not meet the requirment for this update"

HELP ME !! Here is some screenshot to show you what im exactly facing up with...
