Navigator 6 IPAQ Freezed at Splash Screen

Hi

Navigator 6 on SD Card
Windows Mobile 5
IPAQ hx2190

I baught a SD card with Navigator 6 and maps over a year ago. Its been working completely fine, until recently it just stopped working.

It now freezes at the spalsh screen, and i cant do anything with it.

I have uninstalled the program, deleted all references in the program files directory, hard reset the PDA, and every combination imaginable!

I reinstall the software, and then sometimes i get to choose what country (UK) and it does the same again. it would seem that i am missing some files that i need to remove to make a complete reinstall.

I'm looking for some advice on either reinstalling it from scratch, or a fix to make the freezing screen go.

When i contacted tomtom on email support they wanted me to connect it to tomtom Home, i've never had tomtom home, and i dont want to use it! I just put the card in, and it works. I will get home if i have to, but i imagine that i can just reinstall it?

Any help greatfully recd

Thanks
