Help new (10/28/2012) iPhoto won't work and crashes my 2011 Mini

Question

Bought New iphoto and it won't let me import my photos from a  time machine back up or from optical disks. 
Import goes all the way to the point where it says finishing import and the computer restarts.  The photo library is ,of course, corrupted.
Got a small cd of sum photos imported, but there were at least 2 copies of each photo and when I was looking over the photos the computer restarted again!
Other strange thing is that it took almost 24 hrs. to download the program.  That's longer than Mountain Lion took.  Is there an easy way to uninstall and re-download it?
Any help would be greatly appreciated!!!

Answer 1

to reinstall:
To re-install iPhoto
1. Put the iPhoto.app in the trash (Drag it from your Applications Folder to the trash)
2a: On 10.5:  Go to HD/Library/Receipts and remove any pkg file there with iPhoto in the name.
2b: On 10.6: Those receipts may be found as follows:  In the Finder use the Go menu and select Go To Folder. In the resulting window type
/var/db/receipts/
2c: on 10.7 they're at
/private/var/db/receipts
A Finder Window will open at that location and you can remove the iPhoto pkg files.
3. Re-install.
If you purchased an iLife Disk, then iPhoto is on it.
If iPhoto was installed on your Mac when you go it then it’s on the System Restore disks that came with your Mac. Insert the first one and opt to ‘Install Bundled Applications Only.
If you purchased it on the App Store or have a Recent Mac you can find it in your Purchases List.
About importing:
1. Do Not Import a Time Machine back up. These need to be restored not imported.
2. Where did these optical disks come from? Again, if they were created in an earlier version of iPhoto you do not import from them.
