After playing through the story i did a fresh reinstall and redownloaded the 64bit version.
Put the Texture Mod back in and reloaded the Hoth mission. Works perfect now. Thank you very much.
Thanks for the reply.
I am pretty sure i did. But since it is currently working, i am gonna keep the current configuration running.
If it fails again at some point or i finish the campaign, i am gonna try your suggestion.
