Failed to save package list!

Question

I am trying to add DM packages for my tasks in eData --> Organize Package List menu but after adding the package group and the DM package to the group, when I try to save it, i get an error message "Failed to save the list!" and the packages disappear. I have checked my profile and I do have the required authorization etc. Has anyone else seen this kind of error on BPC 7.0NW SP5. Any idea what might be going on?
Thanks.

Sorin,
thanks a ton for your efforts. I did try adding the package group and save it first before attempting to add the DM package. The problem is when you add the package group the message says that the package group is added successfully. Then when you try to add the package and save it
eData --> Add package group in ADMIN folder --> Message "Package group has been added successfully".
After this step I can see the package group iunder the Application folder
Next Add Package Package type Process Chains. I select /CPMB/LEGAL_CONSOLIDATION --> Give it a name say LC, in the same folder as the one created in previous step. Check the task type User Package and Admin Package --> Select. The selected package shows up in the respective folder. So far so good.
Next when I click Save --> "Failed to save package list!"
When I try to look under eData --> Organize package list --> all the folders are gone! (Even one from before that was, I believe defaul Data Management).
I check under eData --> Manager Tream User Package Access: I don't see anything.
I have the proper security in BPC security settings (DM etc.).
I am at wits end!
