Hello, from yesterday i began to start having some problems while checking my mail by clicking on the mail button inside live messenger.

From time to time instead of opening my inbox correctly, it opens http://www.msn.it/hotmail and i get 'The system cannot find the file specified. ' as error.
The only solution for now as far as i could get, is to completelly close WLM and restart it and then it works. Is that a new bug or that's my pc problem?

I already used a repair installation for WLM.
