ok, i spent the whole day, with binge watching & tinkering and i found out how to fix this problem. And it's pretty simple :D
Navigate to the folder c:\users\yourPCname\documents\my games\skyrim
Delete both .ini's (backup them first)
Then start Skyrim normally (just the normal skyrim launcher), it detects your optimal graphic settings and writes new .ini's.
Copy both ini's and search for the same names in your Skyrim PM installation folder.
There are serveral copys of it, replace them all with the new ones from your my games folder.
I hope it starts after. Mine does...unfortunately it crashes just before the menu comes up. But hey, i got 3 seconds further in just 10 hours, maybe i'll be able to play on tuesday XD
