Vista - autocomplete

I have been using MS Office Word 2007 for several years, but recently upgraded from Vista Ultimate-32 bit to Vista Ultimate-64 bit. Before this upgrade (and through no effort on my part), when I would begin to type either the name of a day or a month, I would get an automatic "tip" that would finish the word by pressing "Enter". This autocomplete function, which was very useful, no longer seems to be working since the upgrade. I checked Word Help, and it claims that "AutoComplete is still available for the current system date, months, and days of the week." Is there something I can do to reactivate it? Any help with this issue would really be appreciated. Thank you.

I have had a look and tried to reactivate it on my system.
It is in the word options, proofing, autocorrect, smart tags.
You an insert the date by clicking on the insert tab then date and time.
I have not been able to get the smart tags to work either.

I had also posted on a MS forum and just received this link: Date auto complete in Word 2007 - microsoft.public.word.newusers | Google Groups

I followed the thread and the instructions, and the autocomplete function is now working again.

Glad you got it sorted.
