I changed the PSXT livery library list to individually test each collection. So, FSLTL on its own, then MTL on its own, JF on its own (which a fresh livery scan in-between) and that narrowed the problem down to AIG only. Then I did what you suggested, removed that folder, re-ran 'AIGTech - AI Manager' and did a Verify Setup (and all other updates it prompted for). Now working perfectly. Thanks, very much for the help, appreciated!
