Sage Estimating - cannot use "assembly, model or item takeoff".

When I open Timberline, and select the "takeoff" tab,  I cannot click on the "assembly, item and model takeoff" buttuns.   They are grayed out.   It cannot fix this.  Any suggestions on why I cannot click on these?  Seems like I have restricted access on this program.  I.T. says I have full access. 

Thank you in advance for your help.
