Very Confused - iPhoto version 9.1.3 will not launch, just infinite spinning spokes

Question

Ok, so I am a recent apple convert from Windows, which I have used all my life until I go a Mac Book Pro for Christmas, so I am a little unexperienced when it comes to all this stuff. I am running Mac OS X 10.6.7, and have had no problems until this past week with the iLife software. I went to open iPhoto on Thursday, and got this screen, with the infinite spinning spoke:
I wasn't sure what to do, so I just let it sit...for over 24 hours. I spent much time here on the support website reading the discussions. I have tried deleting the com.apple.iphoto.plist file from the preferences folder, deleting the cache in the Library folder that was in the iphoto folder, I downloaded iPhoto Library Manager, tried the rebuild function and get the error: An error occurred trying to open the database at /Users/Becky/Pictures/iPhoto Library/Database/Library.apdb (14). I then noticed while in iphoto library manager that my iPhoto Library is version 9.1.2, which I assume is the problem since my iPhoto is version 9.1.3. When I hold the command+option keys while clicking on iPhoto, my computer does nothing, like it doesn't even know I clicked anything, however when I hold just the option key and click iPhoto it allows me to select a library, which in turn gives me the screen above. I don't know how to make my library update, or if that is even the problem. Somebody HELP!!

Answer 1

Make a temporary, duplicate copy of your library and apply the three fixes in order as necessary.
Fix #1
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your HD/User/Home()/ Library/Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your HD/User/Home()/Library /Caches/com.apple.iPhoto folder. 
3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot. 
Fix #3
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next  window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
