Well, it looks to me like somehow the identification information in the pocket pc is screwed up. The information it should show in the screen you posted should match the information you posted:
Product Revision Level : 3.0
ROM Date : 11/15/02
ROM Revision : 1.00.45 ENG
OS Version : Windows CE 3.0
Whenever a user attempts to update their pocket pc with a ROM or Firmware update, one of the 1st things the update application does is check to make sure the pocket pc's ROM and language are compatible with the update. If they are not compatible, the update application stops, posts a message, and exits. That's what is happening to you now. There may be a way to avoid this compatibility check, but I am not familiar with it.
Technically, your pocket pc's language is in English, but there seems to be some inconsistencies somewhere in the pocket pc that confuses and mistates your pocket pc's language to the upgrade's compatibilty checker. Even through you don't want to really change the language of your pocket pc (you just want to fix whatever is causing the confusion) you could try the procedure for changing the language of your Pocket PC that is well documented in the forums here and in RICOUK's "My PDA" page found here (scroll down the page a little and you'll see the procedure):
