Word could not recover Building Blocks.dotx

While working on a Word macro, Word started crashing. This happened 4-5 times in a few hours. At one point, the macro got into an infinite loop. I used Ctrl+Break to interrupt it. I don't recall if the first Word crash happened before or after the infinite loop.

After one crash, I got a pop-up message saying "Word could not recover an automatically saved document from the last session. (C:\...\1033\Building Blocks.dotx)

I have tried restarting Word and rebooting the computer. The computer reboots without errors and Word restarts without errors.

I searched the KB and found a link to a page that offered to fix the problem for me. Here's the link:

http://support.microsoft.com/kb/925175/en-us#FixItForMeAlways

The instructions said I would get a pop-up asking me if I wanted to Run something. But when I clicked on the Fix It button, I got a pop-up asking if I wanted to Save a file named MicrosoftFixit50722.msi. I said "Yes", it saved the file, then did nothing.

Is the problem with Building Blocks.dotx caused by or causing the Word crashes?

What do I need to do to recover?

PS: I did a search of my hard disk for "Building Blocks.dotx". This is what I found:

10/27/06 08:32 Building Blocks.dotx.save
10/27/06 09:32 Building Blocks.dotx
10/27/12 11:32 ~$ilding Blocks.dotx.save
10/27/12 11:32 ~$ilding Blocks.dotx

They are all in C:\Documents and Settings\Administrator\Application Data\Microsoft\Document Building Blocks\1033.
