Upgrade from Contribute 2 to 3

[pismojudy]

I upgraded from Contribute 2 to Contribute 3 by way of the trial version of
Contribute 3 - the paid version is in the mail. And I find that I can change
almost nothing on any of my web pages. The Tables buttons are grayed out and I
can't change font sizes or make other formatting changes. All I can do is
change text.

Is this because it's a trial version or is there another explanation? The
person who manages the website said he didn't do anything to cause this
problem.:confused;
