I have encountered a large problem.
Somehow, my Arcadia textures with the NCC-82681 registry have overwritten all the Enterprise F and other Century textures. When I put the correct textures back in place, the h1 texture stays. In other words, the Century has yellow deflector dish (still called the Arcadia) and teh Ent F has blue deflector, only half activated warp engines (like they should be) yet called the Arcadia. I open the h1 textures of both ships and it shows their names e.g. USS Century instead of USS Arcadia. I replace these textures again and again, I even remove them from the main texture folder (into a backup) yet the Arcadia 82681 textures are still there. Argh!
