Did you end up with a Zip file within a Zip file? I've downloaded batman-1_05_0.spk1.zip. I've extracted that to a folder so now have files .003.000 and .003.002 which look correct. File .003.001 is another Zip file. I've extracted that which has given me .003, NOTE: not .003.001. If I try to rename it to .003.001 it just changes it to another Zip file which isn't extractable.Well eventually a full download.
The update went smoothly and working ok.
As mentioned above the skill shot lights are now reversed. So less of a skill shot
