Hi,

Is your ultimate goal to import Rational Rhapsody models or Rational Software Architect Models?
What is the version of Design Manager you are currently using?
What is the full error message you are getting?
Are you able to perform other operations?
If all the permissions are allowing you to perform imports as shown below:
 
then make sure you have a valid license for Rational Rhapsody Design Manager - Design Manager  or Rational Software Architect - Designer for your user.

Regards,
François

Hi,

How is the message appearing?
What do you see in the dm.log (located in <server_install_dir>/server/logs if you are using Tomcat and if you are using WebSphere Application under  <was_profile_dir>/logs).
With a user who does not have a valid license, I can see the same error "blinking" each time I press the save button on an import definition.
If I then go to dml.log, I get an entry like:
2014-08-12 10:13:54,158 [        http-bio-9443-exec-266] [] ERROR com.ibm.xtools.rmpx.common.exceptions.RmpxRuntimeException  -

Can you tell us which kind of license you activated and if none of the licenses applied to your user are expired?
Are you able to perform other DM actions in other project area actively managed with DM?
