My Passport Essential don't work with win7

Hello;

I used to work with winXP it works OK,last week I change my computer to new one with OS Win7.

When I connect the passport  the driver installed correctly and it ask me for my password I enter my password , after some time I receive an error message there is a problem to continue working.

First. Is the device suppose to work regularly with win7 although the documents now are  in a different place ( In windows 7 in user directory and not directory document and setting like at winxp) 

What should I do.
