* FILE>OPEN selection from the dropdown menu in the upper left Task Bar of the Graphical User Interface will not work.
- Problem Description:
* Selecting FILE>OPEN presents an error box with the message "Could not complete your request because of a program error."
4) Trouble Shooting:

- Fully updated photoshop.
- Updated the computers version of Java (Java 7 Update 45).
