Move all files to another server

Hi there,
I have recently upgraded my account so that I can export the codes to .net,
this is the published prototype, everything seems well-positioned and smooth.

However, after uploading all the exported files to .net, some items are misposition or overlapped, symbols and the entire nav-bar are gone, the animation effect doesn’t work…

It took me hours finding the causes but no luck, could anyone spot what I am missing? Or did anyone ever have a similar experience? :confused:
