WET Error - Some Of The Files Might Be In Use

I am migrating from XP 32bit to Windows 7 32bit. When I run WET to transfer my XP files to Windows 7, I receive an error for every file. None of them transfer. It tells me that it can't continue until I fix the errors. When I view the errors it tells me that "Some of the files you're transferring might be in use. Close your open files and try again or click skip to continue without these files." After numerous failed attempts, I click skip to see what happens. It says "Your transfer is complete." Although all the files didn't transfer, the report says successful. The folders are created, but no files are in the folders. It says "Folder Empty." These are all my files. I need them.
