Win 7 Rollback (latest updates) & then System Restore back days before those updates...still no upload using WU module in Weatherlink after years of success, it's now broken. I guess deleting account and re-doing it may be what's next. I have CWOP and SGXWFO data uploads working fine from within Weatherlink, it seems to be WU that's shut the door somehow. I am just about ready to dump WU all together, too much work and frustration over the years since Weather.com took over.
