missing mssp3pt.dll

[y3by]

hi ppl
In my organisation , i've a pc that gives me an error in word, and closes the aplication...

the machine is a w2k pc with office XP...

i saw the event viewer and find the following message

"Faulting Aplication winword.exe version 10.0.2627.0, faulting module mssp3pt.dll version 3.1.0.10 , fault adress 0x0000465f"

My question is, what solutions do i have!?

I've reinstaled de office , but it didn't work.
If i get this dll in a pc that don't have problem and put it there it should work!?
did i have to manualy registrate this dll!?

i'm a litle bit lost!!

thanks for reading, and more thanks for helping!!


ps sory if i repeted the post facing trouble with IE
