I am having this same problem. I tried accessing the LawHub website from the link they sent in the email and though the LSAC.org. For both of those, once I login the page is blank and keeps cycling over and over until I close out of it. I tried the suggestions that Juliet posted above but those didn't work either. Is there any way that my 7Sage account can be unlocked for now without linking it to the LSAC page? I contacted their technical support and they have yet to respond to me.

You need to take way more practice tests. I didn't start hitting above 160 until I took ~20 practice tests.
