I just changed from an older Mac and had the software transfered to my new OS X 10.8.3 and now most of my CS4 apps don't function even after running updates. I logged into my Adobe Account thinking I could re-download and install CS4 fresh on my new MacBook, but I can't find the download links to my software. How do I re-download CS4?
You can download the trial version of the software from the page linked below and if it is able to be installed you can then use your current serial number to activate it.
Be sure to follow the steps outlined in the Note: Very Important Instructions section on the download pages at this site or else the download will not work properly.
