Animated character import causes crash

Hi
im new to UE and im struggling to import my player character into UE4. Yesterday i managed to import the character
but the animation didnt work. I had one animation, a walk cycle. A animation did appear in the content brower but
when i opened it to play it nothing happened. Today UE keeps crashing when i try to import the character again. I
am getting the following warnings when i export FBX from Maya LT but im not sure what they mean. Is there something wrong with the animation i made in Maya?

  1. Warning Complex animation baked(1)
    360 attributes had complex animation. Complex animation was exported as baked curves. (25200 evaluations done)
    2.Waning: Animation curve tangent type changed to User)213)
    The plug-in has changed some animation curves tangents type to User to ensure interoperability. This mode change will not affect the animation curves’ values
