Word 2007 doesn't stop repaginating

I have this problem on my laptop, I open any .doc/.docx in Word 2007 and it doesn't stop repaginating. the cursors goes as working and in the bottom bar it says that word is repaginating...
When I installed it in the beginning all worked ok but now it doesn't anymore.
I removed it and installed only word and excel* 2007 but again.
Excel files are working ....
I found a lot of people complaining about this but in Word 2003 and there was some steps to follow but they are not present in 2kk7 anymore.
Someone who got throught this and knows a fix? plzz
