Desktop WinPro7 version upgrade (Downloading blocks 15%) has stopped here, at 15% -- now 20 minutes. Well, sorry... Anyone have this issue? Previous version has worked fine for two months.

EDIT(1) Went to Telegram support and tried the apparent solution... Delete node.db (or move to desktop) /Users/{your User name}/AppData/Local/Beam Wallet/... then restart. Looked good but has stopped again at 15%.

EDIT(2) I had to delete the entire Beam Wallet directory and reinstall the previous version still in my download folder (BeamWallet-1.2.4419) and it's at 38% after twenty hours. I attempted a fresh install of 2.0.4739 on a second PC (i7 quadcore 2012) and it stopped at 15% but I've left it running with no change for 18 hours.
