Sorry if this a known problem and I’m just cluttering the forums but every time I start the launcher it prompts me with a download for a new build. It will ask me this even if I download it, close the launched, and start it again. It’s the same download every time and I can’t not download it.
Could you add a screenshot of the download/prompt? It’d be more useful, as we could then diagnose the problem with a visual image.
Try downloading the updates and installing them manually from here: viewtopic.php?f=16&t=1271
