Ok, there are News...bad news for me, maybe good news to locate the Error.

after you last Post LightningLockey i load the game again and try to click on a skill to check if there is a movie playing, but the game only crashes and so i load an older Savegame to try this and...it also crashes and than i load after two more tries with older Savegames i loadet the oldest savegame and it is also corupted - the Skillerror is back and in everi existing savegame. I dont understand that because i could play the game bevore without this problem and now every Savegame is killed....

it seems i will never play divinity 2...

I will answer the other questions later, iam at work.
