AzMan MMC SnapIn Error while opening SQL Server Store "Cannot Enumerate Child Objects. The following problem occured: Access is Denied."

We have AzMan configured with SQL Server Store, which contains Operations, Tasks, Roles, BizRules. I have opened the store in AzMan.Msc SnapIn, I am able to see Operations, Tasks, Bizrules, Roles, Groups. I have added more Operations, Tasks, Bizrules, Roles. After adding these, i have closed the AzMan.Msc and try to re-open the same store again, i got the following error.
