Avast Passwords for Mac Version 1.5.4

[Kari22]

I made a mistake (?) to update my Avast Passwords to version 1.5.4.
It doesn't start. Keeps saying "Avast Passwords didn't start properly".
All I can do now is to Quit it.
How can I downgrade it to previous version? ... or is there a way to do something else?

this didn't help.  I'm having the same issue.  Am I able to use terminal to backup the vault or password files somewhere and reinstall and then restore my password file?

It does help if you post in the correct forum.

Given the topic, I believe I'm in the proper forum 
Avast Passwords for Mac Version 1.5.4

I installed 1.5.4 this morning and NOW I get the "Avast Passwords didn't start properly"  QUIT

What do I do to fix this?
