I tried your suggestion of unchecking the license warning. Mine wasn't checked, so that's not the issue. I deleted the window's updates but that didn't help. I re-downloaded LW just to make sure I wasn't missing any files. That didn't fix it. I downloaded the beta version (4.13.2) of LW. Some things download very slowly, others (even with 100 sources) just say they're connecting and never download.
