hi untill few hours ago I could finely launch and play skyrim , now I can't I get the splash screen with play , options data files etc , I can click on all buttons but when I click on play nothing happens ... and I have to alt cntrl canc to quit it .... I have made file convalidation and said 1 file was not convalidated and will be downloaded again , I did so and it didn't help , so I redid and it says always that finds a file not convalidated and redownloads ... nothing works ... now I have not modded or done any changes to the game since last time I used the software so there had been any kind of weird updates or something that is causing this or what can it be?
