Why does Photoshop elements 9 not start once I downloaded Wacom drivers?

Question

I use Photoshop Elements 9, it is fully updated.
I recently switched from a bamboo tablet to an intuos. Previously, my bamboo worked perfectly. Elements could detect pen pressure and worked fine. Now, elements (the editor, not the organizer) has stopped booting.
However, I recently got an intuos and once I downloaded the drivers, Photoshop would stop booting. For example:
I try to open up a photoshop file, photoshop would stop responding.
I open up the welcome screen and click on edit, the edit button shows that loading sign for awhile before returning back to the normal edit button. After that, nothing happens and the editor doesn't open.
I try to open the editor directly, it stops responding.
There were however less than ideal ways I could force elements to boot. I could open up Wacom Tablet Properties, and delete the Adobe Photoshop Elements preference over there. When I do that, photoshop boots instantly even if it was in the middle of not responding. Even when I try to boot with the welcome screen and the edit button just fades, as soon as I delete the preference, elements boots. Even if I was waiting for fifteen or twenty minutes before deleting the preference, elements would boot. Another way I can get photoshop to open is using the wacom tablet preference file utility to delete the preference.
However, when this happens, pen pressure doesn't work and the cursor is really laggy. The disc keeps appearing over the cursor.
Other stuff I've tried:
Uninstalling and reinstalling the drivers. I've tried using the disc the tablet came with. I've also tried the installing the driver from the website.
I'm not sure about resetting the photoshop elements preferences. I've tried clicking ctrl+shift+alt and clicking to open photoshop but it just opens up the properties window. (But isn't what I did with wacom tablet preference utilities achieving the same thing?)
I greatly appreciate any advice you could give me! Like if this is even the proper place to ask?

Specifically, this:

But it is also very important to delete any existing preferences after a major OS X upgrade. For PSE 6 that would be:
com.adobe.Photoshop.Elements.plist
Adobe Photoshop Elements 6 paths
Adobe Photoshop Elements 6 settings
They're in your username>library>preferences. Here's how to find it in 10.9:
