File does not exist - on_extractedTex.jpg

Hi all

I am trying to open an old file of mine, but I have a problem doing so. The problem occurs when I enter the material tab of the file. The file generates an error in the command-line, and does so every few seconds. You can see it here:

I have tried a google search for on_extractedTex.jpg, but with no luck. Also tried purging, and importing the file into a fresh file - same result.

Can someone help? Thanks in advance
