This is almost certainly a failed pack job. Did you update the asm file properly? What packfile did you put the image into? Did you try to rebuild misc.vpp_pc? I would just take the files from that packfile that you updated and drop them in the root folder as that will get picked up before the files in the packfile.
I could not find asm for interface-backend.cpeg/gpeg <-- thats where I put DDS and I packed the .cpeg and .gpeg into misc.vpp_pc
and drop in my interface-backend.cpeg/gpeg into root is that what files you mean just to make sure
ill try to do repack all the files when I have time to see if I done it rong if ther is no asm I just untick update asm_pc am I doing somthing rong ther
