It sounds like you have followed the correct procedure, but make sure it is 'auto-correct'.

..

Most Nokia handsets have a button on the keyboard to do this.
Try looking for a button that shows "T9" on that.
Long press it, and the predictive text mode will be toggled.

You can enter text in two different ways: the traditional text
input indicated by , or predictive text input (built-in
dictionary) indicated by .
To use traditional text input, press the key marked with the
letter that you want repeatedly until the letter appears.
To turn on predictive text input when writing text, select
Options > Dictionary and the desired language; to turn it off,
select Options > Dictionary off.
To use predictive text input, do the following:
1. To enter the word you want, press each key once for a
single letter.
2. If the displayed word is the one you want, press 0, and
start writing the next word.
To change the word, press * repeatedly until the word you
want appears.

If ? is displayed after the word, the word is not in the
dictionary. To add the word to the dictionary, select Spell,
enter the word (using traditional text input), and select OK.
Tips for writing text with traditional and predictive text input:
• To add a space, press 0.
• To quickly change the text input method when writing
text, press # repeatedly and check the indicator at the top
of the display.
• To add a number, press and hold the desired number key.
• To get a list of special characters when using traditional
text input, press *; when using predictive text input, press
and hold *.

You must disable your Predictive text option, T9® predictive text mode allows you to type words with only one keystroke per letter, and the phone interprets what word you want. For example, to type the, press 8, 4, 3. To enable/disable T9® predictive text mode, select Options. Scroll to and select Prediction on or off.

Hi,

For you to switch to predictive text or T9, just go to your "Text Message" window, when on that application window please select on your "options" button on your cell phone.

You'll have a pop up with scroll options that would either say 'predictive text', just ok the T9 or "Predictive Text" option and you would be able to have predictive text switched on.
