Hello Aki,

You are right, the same error happens, even if I do not use the master 
password.

The weird thing is that it happens only with one specific account. For 
this account, the virtual folders I have don't work, but they work for 
the other accounts.

I do not have too much time to investigate now, but I will continue this 
weekend.

Kind regards,
André
