i dont start in act 1? im in the last act ?? is that normalt? i did kill hades and enter the portal, and ended up in the last town....then i will start the secound time, and then its starts up there at the last town and not act 1.............

Are you using your old character? If you do so, as far as I remember, you have to choose the next difficulty level. Since your first playthrough with every character is always on "Normal" you now have to select "Epic" in order to run throught the whole game again.
Otherwise you will just start at the last fountain (or is it called well) you visited on normal difficulty.

i did,. but it end up in the city of athens :-( but is correct if i start on normal, im on the last boss area, but when i clcik epic, its start out side city of athens :-/ i cant start a new game

Okay, weird. Are there any portals activated on epic difficulty?

yea all uptil athens :-/ its weird, i never played it on epic with this char. did just end it first play t. and then i enter the portal she makes, and then to credits screen, and then i go into next mode, and start up in front gate of athens :-/ i did try to travel to start town, no quest there :-/ maybe my char is bugged

Are you completely sure you didn't play through the first act on epic difficulty before? Because you can always go back to lower difficulties and start right at the end. This seem most likely from your description.
