I recently started having problems opening any of my Office 2003 Professional programs. The files seem to open, but an error pops up saying that I'm missing a file named PS561401.cab, and can not open without reinstalling the program. I don't have the installation disks for Office, as this computer was my husband's old work computer.

Any suggestions? I'm not sure why there is suddenly a problem when they used to work for me.

Thanks for any advice you can offer!

Have you tried a system restore to when it worked ?

Stupid question, but how do you do that?

Thanks.

Under Accessories>System Tools, you'll find System Restore.

If that doesn't work and you don't have the disks you will need to purchase a legal copy.
