IMAP/POP3 incoming mail widget

Hi there,

I am trying to build an email client using the widget provided in appstore: IMAP/POP3 incoming mail widget. I downloaded encryption module as well but i cant get the widget to work. I can connect to my emailaccount in step 1 but in step 2 I get: an error occured popup.

Modeler 6.8.0

Error:

• The string provided is not an encrypted string. Returning the plain string.

• Error while encrypting string: Key should not be empty

Anybody a clue ?
