I installed anki 6 months ago and it worked great for me. When I update it to 1.2.11, it crashes when I want to download plugin or deck. I googled and some users claim that by installing new verson 2 through anki website all this bugs would be solved. I install anki 2, but now it crashes in opening. The crash error for 1.2.11 is

Code:
Error was:
