I purchased the 2018 version of QB in May.  I've had no issues up until yesterday when I got an error box immediately after putting in my pw.  It appears that the program opens but I get an "unrecoverable error" box with the code 01770 37507  I've rebooted, run update checks, virus checks and I've even installed the program on my laptop and the same issue is happening.  Please help.  I use this every day!
