I do not have harpoon installed. My crashes come after the game begins. They come after a few seconds. I can login again and move for a few seconds and then, bang, the game crashes again. I cleared the caches etc. with no changes. Eventually I reinstalled the entire game and used an earlier version of the mod installer.
First time I've had problems with the installer -- which is rather amazing given how many mods it handles.
Thanks for all the work on it.
