Google rejects reinclusion requests when they still see problems on the site and/or when they feel that the webmaster didn't do everything they could to fix the problem, whatever it was.
The disavow file alone will not solve your problems, you need to actively try to get the links off the net as well. Contact as many webmasters as you can and document the results, Google wants to see some effort.
It's my guess that if you file your request 5 mins after submitting a disavow file and 100% of the links in the file are still on the net that the request will be rejected.
