Thank you for the post.
FileMaker files already in the .fp5 extension can be opened and converted directly with any version of FileMaker Pro 7 through FileMaker Pro 11. The FileMaker Pro 6 Trial should not be required. The FileMaker Pro 11 Trial can be located here:
If your FileMaker Pro 11 Trial is already expired on that computer, then you can use another computer. If you do not have another computer to use, and you are located in the U.S. or Canada, then contact technical support toll free at 1-800-325-2747. The hours are between 7 AM - 5 PM PDT.
If you are located outside of North America, then locate the technical support office nearest you from the following link:
