Hello, sorry to introduce myself to the forum this way, but I think I have a big problem, the laptop I'm currently using is my boss's, and I can't get outlook to run. Wich is a HUGE problem for the bussiness. One week ago it worked just fine, then suddenly office sterted coming up with this window saying MAPI cannot find the mspst.dll root, I click accept and it closes. I mean, all that's been done this week was actualizing office to all of it's functions, for word and excel mostly, outlook worked just fine.

We have Office 2010 pro
Win 7 64 bit

I've tried re-installing
uninstalling and installing again
repair

I don't know what else to do, please help.
Thank you
