Apex Clothing Crashes UE4 or doesn't work at all

I’ve been trying to get Apex to work for days but nothing, I tried exporting my mesh into centimeters, meters, used multiple Apex Clothing Tool versions, I even used the Maya plugin, I tried pretty much anything but whenever I get to import and link my apx/apb file to the material, the engine either crashes or the mesh just disappears.
Any idea on how I could solve this problem?

Thanks.

seems to me you are running low on vram. perhaps you should consider dropping your 970 and instead buy amds rx 580 8gb for the optimal performance, stability and speed.
