FSX Gmax windows 10

Hi I'm new to FSDeveloper. Thanks for the team allowing me in. My windows 7 computer broke. Got a new one with windows 10. After struggles got FSX and SDK to work. But can't get any models exported from gmax. brings up all sorts of errors. Tried all compatible settings. Did everything the same way when I had my previous computer. Can anyone help please? Or am I doomed with windows 10 ?
We really need more detail.

Have you set the correct decimal separator? Do you get the FSTools menu in gmax? Show a screenshot of your error message. Post the gmax source so we can run it on our setups and see if the errors persist.

Don't double post.
