Thanks Butters for your replies!

I am just thinking, is there a way to get a log from the Updater? Sometimes after restart I see "Erasing 0%" sometimes I see "Erasing 2%" or "Updating 0%" or "Updating 100%". Ragardless of what I do, after some 100+ attempts I still get the same result. The Updater just disappears without any message. Once when running it with Windows Vista compatibility mode I heard standard windows error sound when the Updater disappeared. There was no window or anything. Sometime when running the updater in older Windows compatibility modes a get the "Out of memory!" warning message form the updater and then it crashes.

I am wondering maybe it gets stuck exactly at the same moment and ther would be a way to see if this is true.

Thanks.
