Trust Squidley to cut the Gordian knot. I think I might have solved the second half of getting in. It seems you need to do this in a particular order. First pull up the BVA site and then go to the tools function and pull up you browser history. Erase it all. Cookies, everything. When its clean go directly back to the bva site and click on a decision. It should work.  I use Google Chrome and I’ve done it twice today. If I close the BVA tab and try to reopen it, it goes to page not found. A browser scrub and it’s back.
