This one addresses the issues people have been reporting with AutoPAR getting in a state where it would show retries occurring and never finish.  Overall, AutoPAR should be more reliable now.  Release Candidate 6 only went to a few people reporting the issues.  This one is labeled Release Candidate 7.
There was alot of testing and troubleshooting that resulted in the following changes:
- Backed off on the "aggressiveness" of the assembly mode in AutoPAR.
 - Implement retries for renaming the temporary .NB2 file to the final filename
 - Fixed potential crash issue for people with really huge download lists.
