[Wine] Office 2007 Stop Working

[webusr1]

All,
I have "wine-1.4" loaded and I can no longer run MS Office 2007. It initially ran for several months, but now when I open any application such as Word or Excel after a few moments the application will crash with a pop-up window and display the following message: Microsoft Office Word has encountered a problem and needs to close. We are sorry for the inconvenience. 

Any help would be greatly appreciated.

Thanks!
