Default Please help: Chrome stopped working

Hi guys... stupid me... I was playing around with Titaniuum Backup and read about the recommended job to integrate update into the ROM in order to free up space. Good idea, i thought.

So, I pressed it and was toasted successfully. Tried to start chrome again and was told that an error occurred and I have to delete chrome first. Well. I wondered as it is a system app. Never mind. Titanium backup pro solves the problem I thought. Deleted Chrome, restarted and installed it.

If now I want to start Chrome, it closes itself and gives a toast that "Chrome stopped working". I can press report or ok. The most interesting part is, that this toast appears 2 times. So, I guess that the process starts 2 times and produces a conflict.

Any idea?
