The update only came today it seems so your issues are probably unrelated, which is unfortunate as it would probably help you to work out what's wrong with it. The issues relating to the update all seem to be during the game. A lot of people altered the exe (myself included) to allow the game to support more than 2gb RAM, which popular theory is what the update is restricting, which might be resulting in all the crashes, however I tried deleting the new TESV.exe file and getting steam to verify the file cache and go on to redownload the file from fresh, with no better results, so there's something in this update that's really screwing things up for a lot of people. I've already had a good 43 hours of gameplay on my character now in just over a week (loving this game) with occasional crashes of a similar nature, but nothing nearly as frequent as this, and I've read some reportsthat the game becomes more unstable as you go along, perhaps in relation to the ever increasing size of the save game file.
