Fill in recipient's E-mail address with: -edited- (copy/paste)
and fill in "Select File to Send" with one of the files (preferable the smallest one) you have a problem with, click send and wait until you see a message that it's done uploading the file (can take a few minutes).
This way I can have a look at it, that is of course, if you're willing to use yousendit.com to send me one of these files.
I got several tools that might fix your file, but without an example I have no clue whether they will be successful.
