Automation question

[djcoq]

When i Installed Virus Ti software at the beginning I could register every automation on my instrument tracks in Logic Pro, without installing or changing any parameter ( midi or whatever).
Since some days I can't register automations anymore.
I would like so much to register automation, you know!
Anybody can help me?
Thanks

It's easy, you must go in track automation and push on LATCH
