iView Importing Business Objects not shown

Hi,

we have Enterprise Portal 6.0 and installed SP13 last week.

Since this upgrade I cannot see the iView for importing Business Objects anymore. When I do a right click on "Business Objects" in the Protal Content Studio and then click on "Import Business Objects" an iView is opened but it is completely blank. By the way the same happens when I click on the Metadata Loader in the DQE.

Has anyone an idea what the problem might be or does anyone know if there are some known errors concerning SP13 and the importing Business Objects function?

Thanks a lot for your help!

Best Regards,

Katharina
