.gdw (read only) not loading on a specific file

Hi Guys,

I have a client who uses Solidworks to open .gdw files to view drawings.

It doesn't load. In other directories the same filetypes load fine, so the file association is there. I just don't know why these two files just don't open.

I can rightclick open with and select the solidworks program and I get the error message "Unable to read file". I don't know what else to try.

Any ideas?
