SAP Knowledge Acceleration

Hi experts,

I downloaded from SAP partners website some files SAP Knowledge Acceleration.

When i open them, sometimes the file asks me the following:

Click Next to continue with the course, or select an activity from the list.

When i click on an activity, i got the following error message:

The bookpage file could not be found!

Does someone faced it before? How can I solve it?

Thanks.

Amine
