1. Was this export running before the update to HF2?
2. Are you using a supervisor user in PIM for media manager or normal users? (Can be checked in the hmm.properties) If you use the normal user, do have the user the rights for media assets?
3. Are there any error messages in the server log?
Is the ExportMime function used correctly?
Thank you all for the response.
We had some issue with the DB instance, after a fresh DB update, the issue was resolved.
