Hello! I am attempting to reinstall CS4 on my machine at work. Initially I experienced error 147:20 a few weeks ago, and I ran their LicenseRecovery.exe tool, and that did not clear anything up. So, then I ran the Adobe CS Cleaner Tool and uninstalled CS4, and then reinstalled it on my machine. When I get to the serial number screen, I am unable to use the serial number provided by Adobe.
If anyone can be of any assistance, it would be MUCH appreciated!
