I don't seem to have an archiveinvalidation.txt in my Data Folder... I don't know how to create one, can some one help?

You don't need the archiveinvalidation.txt. That's only if you can't use ArchiveInvalidationInvalidated or the invalidation in FOMM. Are you playing with a controller? If you are, you won't see the textures while you have it plugged in unless you rename the pc part of the texture path to xbox.
