Hi, I did some hackin my self 🙂
It works fine on my two computers (running XP), no garanties though.
Ok, here it is:
Close ICQ
Start regedit (Start–>Run–>regedit)
Goto:
HKEY_LOCAL_MACHINESOFTWAREMirabilisICQICQLite
change data in:
LiteBannersActive and
LiteCLBannerActive to 0
that will remove ads in main and messege window, google will stay.
But u will have to change permissions in
HKEY_LOCAL_MACHINESOFTWAREMirabilisICQICQLite or ICQ will change the data back….
so right klick on
HKEY_LOCAL_MACHINESOFTWAREMirabilisICQICQLite folder and klick on permissions and change to read only
Close regedit

Thats it ! Start ICQ and the ads is gone.
!! Notice !! U shouldnt tuch stuff u dont know anything about !
Ps. Sorry for my poor english 😀
