FanFictionDownloader.net

I'm using the old version of the Fanfiction Downloader because it has been the only one that worked right for me; until now. It's 4.0.5 version.

I'm trying to download the following story: http://www.fanfiction.net/s/6272950/1/Ask_Again_Later

When I try, I get the following message and I've been getting it whenever I try to download from ff.net. I don't know about other sites, as I haven't tried.
Datei"C:\Ask Again Later.rtf kann nicht erstelt werden. Access is denied.

What the heck is this about and why is it denied?

I tried both 4.0.5 and 0.0.J and 405 won't get the file but 00J does it right well. Maybe it is a setting in 405 that wasn't updated when FF changed their settings.
