You can add the resource only if you have access.
Try with administrator as user name and password as password and theb add.
Otherwise you must know the username and password.
Thanks for the response but i am trying with administrator/password but still unable to add resources to the root folder Resources in the repository.
In an application,if i add it,it comes as a part of the application.My requirement is to have teh Resources in the Resourses tab.When i export an LCA from 8.2 to 9.0 then the resources come on teh root level.Now if i directly want to add some resource from my local m/c to this,i am facing issues.In 8.2 simple drag drop used to work.
May be I am missing a very silly thing but not sure.
There is a specific role named 'Resource Administrator'. Can you try to grant this permission to your userid and upload the resources?
FYI, the super administrator will have all the rights by default; Anyway, just try this option.
