John, Murray and George,

Many thanks for your help.  

I understand the reason of the trouble; so, I will give priority to V8 in
the mathpass file and reinstall V9 to continue the trial.

The problem is that Mathematica 8 is picking up Mathematica 9's activation
information preferentially.  If you did nothing, after the trial period
expired, Mathematica 8 would revert to its normal behavior (because the
Mathematica 9 activation entry would be no good, so it would just skip it).
But I'm guessing you don't want to wait 25 days for that to happen.

Take a look at the output of this:


In all likelihood, you'll see two entries (or maybe more, but the first two
are probably the ones that matter); the first one will have an activation
key corresponding to your trial version, and the second with an activation
key corresponding to your version 8.

You could simply flip them around with any text editor.  Or with
Mathematica.  This code should do the trick (the complexity in the code is
to preserve the position of some comment metadata that might be in your
password file).

lines = Import[$PasswordFile, "Lines"];
lines = Split[lines,
   SameQ @@ StringMatchQ[{##}, StartOfString ~~ "%" ~~ __] &]; lines =
Flatten[Reverse /@ lines]; Export[$PasswordFile, lines, "Lines"];
