My computer guy put Word 7 in my computer. Everything worked fine.

When I went to bed last night, the computer said that there were Word updates.

Today, when I try to open a new document, it said "Microsoft office Word has not been installed for the current user. Please run setup to install the application."

When I try to open an existing document, it said "The command cannot be performed because a dialog box is open. Click Okay and the close dialog boxes to continue."

I just talked to my computer guy and he does not know what is going on.

Please help. I have thousands of documents that I cannot access.
