Undeclared identifier 'TColorTones'

Hi,

After installing the Component-Pack. I only drop a TAdvStringGrid on my form and get the following error: 

[DCC Error] AdvUtil.pas(159): E2003 Undeclared identifier: 'TColorTones'

Any idea ?

(I installed the component pack while the TPlanner and CE Tools where already installed.
After the installation of the component pach, I removed the TPlanner-package.
Maybe that messed things up ?)

regards,

Dirk Janssens.
