Nokia N90 - Word/Excel/PDF Viwer not working

[VijayTriambak]

I have been using this phone since Jan'02, 2006. Recently, I am not able to view Word documents, Excel spread sheets, PDF documents in my memory card.

But I am able to view pictures, music etc.. which are stored in my memory card.

Is there any settings that needs to be changed so that I can view Word files, Excel files etc..?

Thanks,

It is working now after I reinstalled these applications.

The reason was I had changed my memory card and I have lost my previous installation.
