I installed CS4 7 months ago on a brand new laptop and it has worked perfectly until a few weeks ago when it suddenly quit launching. It will only open partially--with the left sidebar showing and is unusable. I tried uninstalling and reinstalling but it didn't help. I contacted Adobe support and they said to come here or buy a support contract since CS4 is an old version. Can anyone help me? I am a professional photographer and need photoshop on a daily basis.

Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift respectively ctrl-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance etc.)?
