Why do I have to re-download ADE every time I try to open an .acsm file? It's a pain! The message I get says that there's a new version of ADE that I must download (hard to believe, since I download files frequently from my library's site.) How can I avoid this constant hassle? Is there another way to open the ascm file into ADE without the constant need to "upgrade"? I'm using a Power PC Powerbook MAC running Sys. 10.4.11.
