Yes. I've been having the same problem for days.  Either the white screen or URL not found or invalid URL. This is beyond ridiculous. It worked fine last year. This year it is garbage.  I can randomly get it to work after I refresh updates. I can get may one or two to go thru. I have refreshed updates 4 times in a row and still nothing. I've posted about this for days. Someone else said  that Proseries suggested deleting cookies (which I did - no help) and changing to Internet Explorer as default. Too bad I have other programs that won't run if I do that. This is absolutely horrible. Two bad years in a row with Proseries.
