Bittrex down for wallet maint, easiest fix seems to be 1) install latest wallet onto new machine, send coins there, uninstall from old machine, remove wallet, reinstall, resend coins back to first reinstalled wallet..
good to know. As stated as well will be doing one last wallet update v 2.0.0.1 will be a required update as there are some bug fixes in it. there wont be any db re-indexing so should be a quick replacement
