I downloaded the CX5 factory service manual from this site over a year ago and used it on several occasions. I went today and all the individual section names poped up. However, when I tried to open anyone of them I get an error message :Can't open a PDA..." " there is something blocking..." I think these were compressed files if I remember correctly. Any ideas about how to allow me to open these files? I really could use them. Thank you. Ed Hayes
