Ilustrator crashes at one location

Hi,

Illustrator crashes when I want to open a file since a few weeks, but only when I'm at home. This error doesn't occur when I open a file at school or last week on holiday. I always use the same laptop. I already tried with changing the WI-Fi and unplugging my USB-drive and Blu-Ray drive, but neither helped. This problem doesn't occur with my other Adobe Software(Audition, Acrobat, Indesign and Photoshop).
