If you're using a PC with Windows: Try rebooting the computer. If its a Mac, ignore that and the rest as I don't know Macs.

Possibility 2: I ran into this problem when I had a FAT32 drive. The file I was trying to d/l (it was a .ISO) was larger than 4 GB. I was able to download torrents that were larger than 4 GB as long as none of the individual files were greater than 4 GB.

If you're using Windows then there's an easy way to convert to from FAT32 to NTFS so that you can have single files > 4GB in size but I can't guarantee it won't futz up what you've already downloaded (neither can Microsoft for that matter).

If neither of those apply, it would be helpful to me (and probably others) to know whether your computer is PC or Mac and what operating system/version is on the computer.
