PSE 10 Keeps freezing EVERY TIME I try to open it.

Question

I have a less than 3 year old MacBook Pro running OS 10.8.3.  I purchased elements 10 NEW in october 2012.
EVERY TIME I try to open elements 10  Editor, it freezes before I can do anything. I have looked in other discussions. Tried to restart from another thread I tried the following...
"Solution 1:
1. Close Elements.
2. Launch the Photoshop Elements Welcome Screen and hold down ctrl + alt + shift as you click Editor.
3. Continue to hold the keys until you see a message box asking if you want to delete Photoshop Elements settings file; click Yes. Elements will open with default preferences.
Solution 2: In case any network printer is attached try to launch without network or printer uninstall or make different printer as default.
Solution 3: Try launching with anti-virus off or removing PSE from conflicting list.
Solution 4:
On the drive on which you have installed PSE,on my machine it is on C:
Go  to C:\Program Files\Adobe\Photoshop Elements  10\Locales\<locale>\Plug-Ins\Import-Exportand you will find twain  plug-in. Remove that plug-in from that location and copy it somewhere  else.
Now launch PSE and check if it works.

1 - I have to force quit
2 - Held down for MORE than 5 minutes. All I got was the spinning beachball. Back to #1
3 - Don't have anti-virus
4 -0 There is no "twain" plug-in
I have also uninstalled and re-installed elements 10. That didn't work either.
Now what????

Answer 1

For anyone else who stumbles upon this thread....
Took the computer to Apple Genius Bar. They found the problem. In the Applications folder>Utilities>Activity Monitor, open and select System Memory at the bottom. Sort by %CPU. Find the icons showing at the left of the list. The ones at the top take the most memory. If whatever you are working on works way too slowly, you may find something above it (or bouncing around-up and down-on the list that is causing the problem (Mail and FireFox in my case). Quit those applications and things should speed up or, in my case, not freeze.
