Occasionally an nzb winds up as a bunch of files with random names instead of the usual "name_of_file.r01", .02 etc - when that happens, sometimes I can fix it by finding the smallest file, renaming it to .par2 and running it - the par2 utility renames the files and I can then unrar them. If i take the same nzb and run it through newsbin, it figures out the filenames. Any ideas ? If necessary I could provide an nzb to test.
