Reset to default settings.

[KDisk]

This is a good program for torrent use. I like the UI, but could use a few more features, All in all it is a good robust program.
My question is this: How would one go about resetting all settings back to default? I am having a problem getting qBT to DL/UL. Installed great then I actually started changing certain values in the Options UI, slowly always (one or two at a time). But now that I have done messed it up specifically the port settings. I am using another program that I have been using for several years now and it doesn't seem to have the same problem. (ie. I can export the magnet link from qBT into the other program and start downloading and subsequently seed the completed file but qBT only connects for searching. I have used the recheck file, and forced a reannounce to no avail. Any ideas? I would like to migrate to using qBT instead of the other program.

I'm searching for a reset to default method too. Thought I'd found it. The link doesn't take me to the answer. Now to find out how to find topic 557.

Considering the original post was 2011, I'm guessing it's not available anymore. I would love to know how to reset to default as well. I've wanted to do it a few times and having to do a clean install instead is frustrating. So annoying that some kind of 'reset to default' isn't part of the options.
