Neither Pages NOR Preview will open
I recently upgraded to ML, but now both Pages and Preview will not open. When I try to open a file, or open the actual application, they look like they're going to, but then they just bounce in the launch bar for ages and I get the nice little rainbow spinner.
Pages I don't think ever has worked since the upgrade, but Preview stopped right in the middle of using it one day and I had to force quit it. I had one image open in it, and tried to create a new document from clipboard, which resulted in it hanging forever with the little spinning rainbow ball, and I had to force quit. Since then it has never opened. Like Pages, It bounces and bounces and never asks me to restore windows or anything. Then it stops bouncing and the little indicator remains under the icon in the launch bar indicating it's open, but if I have tried to open an image, there are no windows for it open. I have tried repairing permissions and restarting without success.
