PSE Editor crashing?

Here are few workarounds :
a) Delete Editor Preferences :

1. Double click on Desktop shortcut > This launches welcome screen.
2. Click on Edit and keep Control+Alt+shift pressed while Editor is being lunched.
3. You will get a screen to delete Editor settings. Choose to delete the preferences and relaunch Editor.

b) If above does not work, rename Twain plugin :
Go to the location where PSE is installed. If it is installed on default location on XP, the location would be C:\Program Files\Adobe\Photoshop Elements 8.0\Locales\en_US\Plug-Ins\Import-Export\Twain_32.8ba.
Rename Twain_32.8ba file to anything and relaunch application.

c) If above doesnot work, try emptying some space on harddisk using disk cleanup utility.
