Visio trial won't work... it claims the date on my clock is wrong?

Help would be greatly appreciated. I want to try the program, but almost all
features are locked because it won't complete activation until I enter the
right date.

The problem is that the date is already right.

It even tells me what the date should be, and then what date mine says...and
they are identical.

It has an "if you believe you're getting this in error, verify here" button
that double checks and tells me again what it should be and I should change
it.. but I can't because it's what my clock already says!

I've uninstalled and reinstalled and all that, nothing works.

Any help is awesome. Thank you all.
