[Trying to reconnect to SL after a long absence...]

I was just sorta curious about what sl was doing these days.  But I cant seem to connect anymore.  I tried uninstalling viewer and reinstalling, to no avail.  My account seems to still be there when I log into the website.  So what is the magic word for returning to SL after 15 some years.  Currently on win10 64 bit.  Thanks for any hints...  Sherman Ochs
