Impossible to move ERROR. Please advise

[acaweb]

Hey there,
I am more of a designer/developer rather than a programmer.  I customized the following gallery for my client at http://collegesoccertours.com/pages/college_soccer_tour_photos.htm (actual gallery is at: http://collegesoccertours.com/gallery/index.php).  He was trying to upload some new photos and now we are getting the following message:
Error Report
The following uploads encountered errors:
File Uploads:
File Name/URL   Error Message
1. P1070019.JPG   Impossible to move.

I followed the troubleshooting guide.  Enabled the debug mode and switched it to only 1file upload capability.  Still getting the same problem and I don't really understand the debug jargon.  I went ahead and turned that off. 

If anyone is willing to help I've created an account for login:

Would truly appreciate your input.

1) Update the gallery. 1.4.2 is ancient and the theme is even older.
2) Don't post admin account on a public forum. Details removed.

Please update your gallery and then do exactly as requested in the upload troubleshooting guide.
