when opening the dmg, I'm getting an "invalid checksum" warning
what should I do?
Too bad Adobe doesn't seem to care about taking care of potential customers. Not very helpful here.
Turns out the download assistant is garbage. FYI, the trial download worked as it should after downloading the dmg file from the direct-download servers, by-passing the download assistant completely.
You can temporarilly switch off Error Checking in the Disk Utility. That will ignore any minor errors and let you mount the dmg.
