Welcome to the forum.
With a memory address issue, as you list, my first thought would be that something else is messing with the memory addresses in your OS. This thread might be helpful: http://forums.adobe.com/message/2031203#2031203
Beyond that, I would look at this FAQ Entry: http://forums.adobe.com/thread/792580?tstart=0
As it says at the top of this forum, we need lots more information:
What operating system are you using? If you are using a Windows computer, is it the 32-bit or 64-bit version? Have you manually gone to Windows Update and ensured you have the non-critical updates, which don't install automatically and often include important drivers?
Do you have the latest version of Quicktime, per the program's requirements?
How fast is your processor and how much RAM do you have? How much free, clean, freshly defragmented space is on your hard drive?
