did you turn on the key board as stated in the directions? (you have to do it soon or it turns off automatically anyway. (also, there's a post in here somewhere from the TO folks about getting it working... might want to look at that too (as they said they found a problem with axims and have a way to fix)
Here is what they sent me... I think it's the same as posted by them

Hope it helps
I have some more information that will help:
1. Turn off the wireless support. Both Bluetooth and WiFi
2. Open the keyboard application and tap the BT tap.
3. Turn OFF/ON the Axim
4. Wait for the "Initializing Bluetooth Support" message to change to "Connection not setup" in the keyboard application.
5. Mark the Secure checkbox
6. Tap "connect button"
7. Press and hold Ctrl+LFn+RFn for 3 seconds until the green light flashes once per second.
8. When the Bluetooth Authentication screen appears use the onscreen keyboard to enter any numerical passkey you desire. Example (123)
9. Tap Ok in top left corner
10. You will now be returned to the Bluetooth keyboard app to enter the same passkey with the Bluetooth keyboard.
11. Press and hold the Left FN+ the corresponding keys to your passkey followed by the Enter key. (Example 123 = Left Fn + qwe)
