> Now, when I preview a project, the program stops running for no apparent reason.
I don't know what 'preview' means, above—do you mean you can't open any projects, at all? It seems like PPro CS5 is encountering missing footage; perhaps you moved the footage files since the project was last saved.

[Think you mean CS6]
If you know of issues with your system, fixing them is probably a good idea. CS6 will still need to find a project's missing footage. Try the trial, and see whether you get different behavior.
I have carefully reviewed the items that should be included in my question. Briefly, checking for updates gets the message "program is up to date"
I have disabled the sound scheme for opening a file and closing a file. Those sounds were always present when the playback was stopped. Clicking
on "start" in the Program window resulted in a brief play then it stops again.
I have checked Windows for problems, using an 88 minute Smart Scan, which came up with No Problems.
Would it be helpful to reload CS5 Premiere Pro from the internet ? If so, how do I get to that point ?
I am willing to pay for tech support via Adobe Access to my computer.
