You may need to disable the Firefox browser preview from the CSS editor on Vista x64.
Can you see if that helps?
Also, are you using java 32-bit or 64-bit?

If you go to Window->Preferences->Aptana->Editors->CSS->Validation then click the plus icon then add .*Unknown pseudo-element.* in the dialog then hit OK it should remove these errors.
