BOE integration in SAP NW Portal via repository manager and km content

Question

Hi BO XI experts,
we try to synchronize a BO folder of BO InfoView through the KM Content in SAP Portal. Following the instructions of the book "Integrating SAP Business Objects XI 3.1 Tools with SAP NetWeaver", we
- installed the system under System Administration --> System Configuration --> System Landscape
- checked settings in the web.xml file
- integrated a Crystal Report through upload and apply of the par-file com.BusinessObjects.pct.masteriview.par
--> the iView for a specific report contained in the InfoView works fine
- integrated the par-file BusinessObjectsKM.par
- created a new Business Object Repository Manager through System Configuration --> Content Management --> Repository Managers --> Business Objects Repository with a new prefix
- went to Content Admin --> KM Content and tried to open the new repository with this prefix
Before upgrading our systems with EP 1 for NW 7 (and EP 4 for SAP ERP 6) this repository worked fine.
After this, we encounter the following error and cannot open InfoView content anymore:
System Error
An exception occurred during the program execution. 
Exception Message:  Your operation cannot be fulfilled due to a network problem, please try again.
Go back and try again
The SSO connection seems to work fine as the a single Crystal Report can still be opened through the iView.
Does anybody have an idea how to solve this problem?
Thank you very much in advance.
Best regards,
Carolin

Hello Ingo,
thank you very much for responding so quickly. Yes, I tried it with a new BO repository but without any changes. I also repeated the upload of BusinessObjectsKM.par - file.
I'm wondering about the result of my system connection test of the BOE system.
There I get the message:
Retrieval of default alias successful
Connection failed. Make sure that Single Sign-On is configured correctly
As the Crystal Report iView works correctly and therefore SSO is supposed to be installed properly, I do not understand why we receive this message. Could the problem, in spite of the crystal report working fine, lay in a uncorrect system configuration?
Before, when the repository worked properly, I did not verify the connection test.
The enhancement packages should not have had any impact on our BO installation.
Thank you for your help.
