Do you have your serial number(s)?
You can download and install some version of CS4 from this site:
Be sure to follow the Very Important Instructions to set your Adobe authorization cookie.
What I’m not sure is if the version downloaded from the above link will activate with student edition serial numbers or not.
thanks but all my info was lost in my back ups and now all I have is an already installed student version of CS4 with no serial # ( not on case, sent by email ) and an error sign 150:30 when I want to use any of these apparently now "out dated" and not supported by adobe apps, all I wanted from adobe was to help me fix this error which I thought I was entitled to after paying for it
Depending on your OS, you may have to copy the python script into Terminal to fix it.
