do you have the expansion registered?

Wanderer's Palace (Hard) two times, Sastasha (Hard), Amdapor Keep (Hard)

Mobs in those dungeons will not give you exp at all save for if you were doing Roulette. I dont think any of the content you did... gives exp to a level 50+ players... You can only get exp from dungeons level 1-49 and from dungeons 51-60. I think that might be your problem.

Level 50 dungeons don't give experience as they were never designed to since 50 was the cap. The only way to yield Experience from those dungeons is through Duty Roulette (and even then you only get the reward exp).
