Hi verwirrt,
Error 150:30 usually comes up if you use timeline or any other software to migrate the files from the older Mac to the newer one or in case of licensing issues.
If you have used a migration software to transfer the files then it's not recommended.
Please remove the files and reinstall CS4 from the disk.
Moreover Photoshop CS4 has not been tested on Mac 10.8.2 and you might face compatibility issues.
Further if you have installed the software from the disk and did not transfer the files from the older mac to the new please refer to the steps mentioned in the Kb doc : http://helpx.adobe.com/x-productkb/global/error-licensing-stopped-mac- os.html
And if you do not have the disk to reinstall the software, then please download from the direct download links available at : http://prodesigntools.com/download-adobe-cs4-and-cs3-free-trials-here. html
But make sure you follow the important instructions on the page before initiating the download.
