PAR files not downloading

[MSWallack]

Since updating to 6.52, some of my RAR/PAR sets don't download the PAR files. They show up in the download list (as part of an expandable group) and the current progress indicator shows that something is downloading. But when I go to the folder to which the files should have been saved, only the .nzb and .rar files show up. No .PAR files are found. When I view the Files tab, they don't show there either. I've tried downloading again, with Bypass Filters turned on. Sometimes (but only sometimes), it will download the first .PAR file but none of the others.

Try 6.53RC1.
