yes you do need to look first before posting, try to find the correct forum section.
The Bit Colider utility has not been updated in a few years. A poor effort in my opinion. However, this utility is purely for listing your own files onto the bitzi website. From memory, instructions for using Bit collider are at the Bitzi site, else come with the collider program when you download it.
To report bad files, you can do that within the LW program itself; see
How to use Bitzi Web Lookup ... & How to use Magnet Links & Direct Connect. The method is slightly different for LW 5, so make a note of that if you are using the new LW 5 version.
This thread will be moved to a LW forum section at a nearby time.
