Hello,

On your behalf, I have downloaded this paint and the file does not seem to be corrupt.
However, it is configured to be installed using the Ace_707 utility so there is therefore no complete aircraft.cfg entry included and this may be your problem.

If you would prefer to install manually, I have made an entry, using the information supplied by the author.
First copy the texture.argentina folder into your CS_B707-300 folder.
To install it, add the entry below to your aircraft,cfg file below the last [fltsim] entry and amend the two numbers in red to the next available number.
I have done this and it displays as it should.

If you are still having trouble, I could temporarily put the files in a Dropbox link but I think this will solve your problem.
