This is Windows 7 / 0.39.15. I have rar password checker mode set to "warn/pause". I do not have the log because I continued downloading the file after deciding this had to be wrong, and the earlier lines flushed out.
It happened when I started downloading the *** nzb posted by NY2. A pop up dialog appeared saying the rar was password protected, and then on dismissal the downloading had halted and only the par and 01 rar had been downloaded.
This is wrong. This rar is not encrypted, it is a false positive. The mp4 inside decoded fine.
Here is the *removed* I obtained the nzb from.
