I saw that same complaint and that was why I was confused. and made this topic, because the main one was close.
I had also skim read the rest of the main topic, and found some others mentioning that the trainer was not working and at least one asked what they were doing wrong.
I do understand that, and while I do mostly agree with what you said, it is sad that the trainer was retired for that reason.
If a trainer keeps crashing, which has happened, I check the topic and see if others have the same problem and then I'd see what they said, and I'd reinstall some software that was stated in the error such as Net Framework and 90% of the time that fixed the problem.
And the 10% was by the trainer getting an update.
However like I said, I DO understand what you are saying, and saying that I am glad that it is back in the requests section.
