Okay since no one seemed to answer my first q, I went ahead and deleted the 1.4 patch(16mb) and all the dlc's I had.
I went online and donloaded everything in this order:
1.Patch1.4 (16mb)
2.Dead Money
3.Honest hearts
4.Old world blues
5.Lonesome road
6.Gun runners arsenal
7.Couriers stash
Went back to my last save and discovered that I've could have done without all that.
Nothing changed, still no new level cap.
I've contacted customer support on this yesterday, tried the forum. Guess the 100+ euro's I've spend on FNV+DLC's doesn't bother the makers.
100 euro's lost is a big lesson learned, I've cancelled my pre-order on Skyrim. And will never ever buy another Bethesda/Obsidian game again!
thx guys for not caring!
