Epicor AQM- IQS Trubox: BIRT reports Training

Anyone use the AQM, specifically IQS -TRUBOX?
I am having trouble finding a resource for training for BIRT reports. I have enrolled in a basic BIRT reports training session by an outside company to get some general knowledge and years ago in school, I had some classes in Java and Java script. So, I am hoping my learning curve isn’t too steep.
For SSRS in Epicor, I was able to get superb training from Epicor and its’ resources.
However, Cority(the new company that owns IQS Trubox) does not provide such training.
Anyone have any experience with this or could point me in the right direction would be greatly appreciated.
Thanks,
Tina
