I'm driving myself crazy trying to get CS4 Master Suite Installed on my iMac. I start the installation, it verifies the disk and starts the install process. After about 2 minutes it freezes at "Checking System Profile" and it locks up the computer, only way to get it back is to stop the task from running. Any one have any suggestions. I'm beginning to hope I didn't waste my money on the suite. Thanks in advance.
