Convert MS Access 98 interface to MS Access 2003

Hi! I've got a DB (in french) with an interface that was programmed in 1995. The DB contains info regarding industries in a specific region. The interface allows to load (search) the information of a company in a table so you can update the information, and there are also macros to produce reports. For now, this interface is only working under Access 98, and I would like to have it work under Access 2003. So I don't want to re-program anything, I just want to be able to use this interface under newer versions of MS Access. I have the BD + interface so if you want to give a look at it, send me a PM and I will send the BD to you. Thanks! Alex
