In order to avoid legal disputes, the LWT software is no longer available.

It seems the creator has decided to delete all the files, discussion forum and all info about the software.
Sure, LWT was becoming a bit dated but I had tremendous use for it during the years before I reached the level that I could read comfortably in my target language. There was a fork made with some improvements a few years ago if anyone is looking for a near identical replacement. Unfortunately it hasn't been updated since 2016.
Thought it was worth a mention since LWT has been a recurring tool through the years.
