ERROR::program you have installed may not display properly!!

hi everyone,

earlier i was using oracle 9i lite5.0.1 and evb3.0 on WINCE.

Now my Pocket pc has new Windows mobile 2003 and when i try to install
the mobile client onto pocket pc ,i see the below warning message on pocket pc.

""the program you have installed may not display properly because it was designed for
a previous version of windows mobile software""

my query is whether i have to purchase new Oracle 9i lite 5.0.2 [supports-pocketpc 2003] ?
or
reinstall my pocket pc with WINCE.

please suggest me the best way out of this OR any better alternative.

thanks in advance
regards
Naveen
