Can you check on SEPM if following folders are available and have content:
...[SEPM installation folder]/inetpub/content/{C60DC234-65F9-4674-94AE-62158EFCA433}
...[SEPM installation folder]/inetpub/content/{1CD85198-26C6-4bac-8C72-5D34B025DE35}
...in the you should find more subfolder with definitions revision as folder name. Could you post a screenshot of these?
