Error 94

[ARRRGH]

I have used the keyfinder program(1.72) before without any problems but now when I try to run it I get "ERROR 94 invalid use of Null" whatever that means. I can run it in safe mode OK with Win XP pro SP2 but when I use it on Office 2003 pro in safe mode I get the same error.
I have tried another Key changer from another site and it gives the same error.
Why does it do this?
EDIT: sorry if this has been asked before but the "search" on this site is not working

EDIT2: I just did a manual search for the above error and found documentation in the Bug section but the fix that is listed (download) did not work for me. When I click on Office in safe mode I still get the "ERROR 94 invalid use of Null" and if I try to run the program normally from desktop I still get "unexpected error" and it refuses to open. It probabally has something to do with other installed drivers or something like that. O well back to the old drawing board I guess.

I have news from Imran, that he is completely re-writing Office part of code, it is that part of the code which is culprit causing errors.
