I downloaded updates manualy, installed them last night and all worked well on this part. 

AutoCAD doesnt show me a note that update is avaiable anymore, so I guess that is done. Thank you for your help.

However, I still have problem with AutoCAD opening everytime I do it for a first time after computer is On. Again today morning it crashed with first attempt and didnt open. I had to "Force Quit" from Application. As alwasy it opened just fine, with second try. This must be some kind of error, bug or whatever. Anyone can help?
