Olympus have not yet released a Windows 7 driver and given that it is an ultra low cost model I doubt that they'll be in any rush to do so.
All you can do is to try and find a Windows 7 compatible xD card reader, but given that xD is now an obsolete format that might also prove to be difficult.
The only remaining option will be to install your current driver onto Win7 and try to run it in compatibility mode.
Sorry there's no straightforward/guaranteed fix here, but these issues always arise with an upgrade to a brand new O.S. version and it often takes up to a year to find out which products will be supported on the new O.S. and which ones will be consigned to obselescence.
