install problems 10.7.2 on MBP 13

hi there,

i'm having troubles to get 10.7.2 installed on my MBP 13 (Mid 2010) - 10.7.1 is running fine and i installed the update for the recovery yesterday. Also i wanted to install the 10.7.2 --> the installation process goes on just bevore the end (progress bar at 95%, moving files) and then nothing else happend (for hours).

i also tried the combo update, exactly the same --> installation goes on just to 95 % and then nothing

any ideas ?

thx, alex
