I wanna solve that, but i have no ideia where to start.
@cazueirobr
try an upgrade to Maltego v. 4. 6.
good luck
ps: for me Maltego v4. 6 works perfectly
cheers . . . 
I had tried to update my maltego, but it does not work 
But thanks by the comment.
are you logged in to Maltego as CE?
Or
it depends on your internet line
Or
your PC causes problems
you have Parrot OS in a VM
or USB stick or permanently installed on a HD/SSD?
cheers . . .
i have been logged as CE.
But i reinstall the maltego cleaning the cache and other things, removing the residual files.
And it’s work.
The problem has been fixed.
Thanks man s2
