Welcome to the forum.
The first thing that I would look at is the amount of free space on the HDD, where you have directed PrE to put your Media Cache. The CFA files are large.
Next, this ARTICLE will give you just a bit more background on Conforming.
For hanging/crashing, you might look over the checklist in this ARTICLE, to see that you have updated, and tuned up everything.

What CODEC is INSIDE that file? http://forums.adobe.com/thread/440037?tstart=0
Report back with the codec details of your file, use the programs below
For PC http://www.headbands.com/gspot/ or http://mediainfo.sourceforge.net/en
For Mac http://mediainfo.massanti.com/
Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project
Or more simply, what type of camcorder is your video coming from? And which project settings did you select when you set up your Premiere Elements project?
