I'VE FIXED THE ISSUE! I can't guarantee it will work, but it worked perfectly for me.
1. Copy a file specific to a CS4 program such as a PSD, AI, or INDD to a flash drive or external drive
2. Create a New User Account on your Mac -- Here's How to create a new account (don't worry, you won't have to migrate your files...)
3. Log out as the original user and log in as the New User you just created.
4. Open your CS4 program and the file you saved to your Flash Drive/External Hard Drive and make sure it works perfectly (if it doesn't, then it's not a preference issue and unfortunately this may not fix your problem...)
5. If all CS4 programs work perfectly, navigate to the "/Users/[user name]/Library" folder on the New User Account (should be less than 5MB on a new account) and copy/paste onto your Flash Drive/ External Hard Drive
6. Log out of the New Account and log back into your Original Account
7. This part gets a little tricky... locate these folders one by one on your flash drive/external hard drive, copy ALL the files within the folder, navigate to the these folders on your Mac's Hard Drive and paste them in place (repeat for all 3 folders)
- /Users/[user name]/Library/Preferences
- /Users/[user name]/Library/Preferences/Adobe
- /Users/[user name]/Library/Application Support/Adobe
After all files from all 3 folders listed above were pasted in place from the External Hard Drive to my Mac's Hard Drive, all of my CS4 programs worked like a dream! I'm not sure how this is different from resetting preferences, but my guess is that a file was corrupted and it somehow was duplicated when I reset my preferences.
I really hope this works for you guys!!
