webdynpro under content admin doesnt work

Hello,

I have an issue with Webdynpro under content administration in portal

When clicked on WebDynpro tab it gives a login page

How do I fix this issue?

I am already part of Administrators group, and I was able to access that before with out any issue, and also have the super admin role assigned to my id

unfortunately there is no error message in the log file

Appreciate any suggestions

Thanks,

Kiran
