I'm not sure this the correct place to put this but.
I've installed the module and found that there's a small bug.
After I assign a sku to a file. I'm forwarded to this address:
and I get a file not found, I suppose this doesn't exist.
I'm not a coder so i'm not really sure what to do about this...doesn't really hurt me that much because it appears to set the file first.
But thought you would like to know.
