See if any of the hits of http://www.google.com/search?hl=en&q=%22The+memory+could+not+be+read%22+%22movie+maker%22&btnG=Search
It could be a codec-issue, but if you say it happens when you open the program (from Start>Run) without even opening a particular movie that's unlikely.
Ok, I will first off tell you what I tried...
Tried super anti-spyware & Malwarebytes
Changed my virtual memory settings
Used two different registry cleaners
Cleaned my ram pins with and eraser
I am out of options- The problem started while trying to open WINDOWS MOVIE MAKER I got the following error The instruction at "0x73692f98" referenced memory at "0x0a2e7000". The memory could not be "read".
Click on OK to terminate the program
Click on CANCEL to debug the program
It does the same thing in camtasia but works longer than windows movie maker, PLEASE SOMEBODY GET BACK TO ME MY EMAIL IS firstname.lastname@example.org
