I started doing a sample image a couple days ago but I was distracted sorry.
Create new folder (example called "A"). Move all good incomplete files to it leaving only the bad incomplete file inside the incomplete folder. Then Delete the old incomplete folder. Next step is Rename the new folder (eg: A) to "incomplete", so it is a 'fresh' incomplete folder. LW will recognise this & use this new incomplete folder if it is in the correct directory location. Sample shows simple way of achieving this.

I'm not sure about your problems with signing onto the forums. One option is to click the option for the forum to remember both your username & password.
Please do not use a password that is identical to either your forum username or your email address.
This can cause a problem. It is also not wise or safe to do this.
It has been set up this way to protect user accounts for obvious privacy & other reasons.
