Technical Issue: PMDG Livery Downloads

Dear Sirs,I attempted to download from the PMDG site the "Canadian Intenational Airlines", "Cathay Pacific 'Hong Kong'", and "Eva Air Old Colors" liveries to no avail. Once saved, I run it as usual with all the prompts, like all the other liveries, but they fail to show up in the MSFS list of PMDG liveries. All other liveries are present, and functioning save the three aforementioned.Any instruction as to resolve this would be much obliged.Thank you,Motty Nolos
