The first page of this thread causes the 550 error - it's browser related. Nothing to do with LabVIEW, or a bug in the forums. On that page the problem is that in one of the messages there's an image that has a URL of "ftp://ftp.ni.com/incoming/contour.jpg" which doesn't exist, hence the 550 error.

I called NI's support, and they helped me fix the problem without
having to reinstall. LabVIEW.ini got corrupted somehow. I
had to rename the old one and restart LabVIEW to let it create a new
one. Thanks for the suggestions.
