Hi Larry,
The file is the vector "master file" created in Illustrator.
i just checked your logo by open it through Photoshop: No problem!
Did you try to open it with a "click and drag" on your photoshop icon or "open as"?...
Don't worry, after the files are approved, i'll send you other formats (.tif .gif etc...)
and other versions (with the text, grayscale, etc).
Best,
Satto.
