I'm having the same problem and I do not have the communicator to call the quest giver...

Just a quick update, Alt-tabbing solved the problem. Thanks all for the help and suggestions. Cheers!

Thanks Stoofa, your suggestion solved the problem!! Will test it again to see consistency..

I'm using ATI Radeon HD 6700. I guess I should go update my driver and see how it goes. Im fine with other FPs, its just Esseles I have this problem. Ah well..

I was running through The Esseles (Republic) and reached the ending scene and then the programme crashed. It said Windows was looking for a solution. Tried it 3 times at it was at the exact same part where the programmed stopped working altogether.
