Help needed

Hi,
I have program to make invoice called "primavera" that uses crystal reports.
I need to insert the logo in the report.
I have downloaded a free trial of Cristal report 11.
When I open the file it gives the message:" The saved data will be discarded since one or more formulas failed to compile"

I insert the logo in the file but the "primavera" doesn't assume the changes.

Can someone help me please?
Thank you.I already encounter this problem. You used a formula in a section expert or anywhere in the report but you delete the formula without delete it first in section expert or anywhere in the report.
