CCleaner and outlook problem

I ran CCleaner at a laptop at work, and after that it haven't been able to recive mails.

It can send mails just perfectly, but im not able to get any mails.

I have tried reinstalling, dial-a-fix and at this moment im trying installing IE7 sp2.

But as i have tried so many different things, im highly doubtful that it will work.

Does anyone know something i don't, that can fix this. :mellow:

Im at the point of almost doing a reinstall of windows.
