Rather than starting a new thread that still doesn't provide the information we need to help you, can you please give us information about your operating system, and whether you've run the updater for ID to bring it up to version 7.5.3.
In your other thread you mentioned you've reinstalled three times. On any of those attempts did youcheck the box to remove your preferences during the uninstall? Did you ever run the cleaner tool from CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3?
