Kubold,
I bought this pack for about a year ago, then it worked perfectly to retarget animations, but now I have started from scratch.
Reformatting my project and after updating I realised that the ue4.8 mannequin skeleton won’t work with my characters skeleton setup.
Even if I switch my character to an A-pose in UE or Maya it won’t retarget nearly as good as it did before:
Everything in my character gets distored, and setting thing adjustet to Skeleton instead of Animation just makes everything in a mix between A and Tpose.
Can you please update the pack with all the animations from the rig before UE4.8?? Then I, and everyone else that has this issue, can redownload it from the Editor Launcher nice and smooth, no hassle 
I have sent an identical message to your user in case you don’t check this thread as often
