ok. i could open cs5 from another user but after upgrading hard drive i reinstalled the cs5 now i can open all the softwares except for After Effect and premier pro that I was able to open from other user account before upgrade. i tried to reinstall/uninstall the software but it says close dynamiclinkmanager before proceeding I am not sure what means.
Then, try again to start the applications.
If that doesn't work, delete the entire preferences folder (<drive>/Users/<username>/Library/Preferences/Adobe) and then try to start the applications.
If that doesn't work, report back.
