Make sure that you have dowloaded and installed the latest Office updates and Service packs and there are a few of them. (Last known Office XP SP is 3). If you are using VBA code (DAO and/or ADO) make sure that the libraries are installed and are available to be referenced. Conversion does not always install the reference libraries and you have to check. If you have any special configurations in the Startup and options, make sure that they exist in 2002. I know of no issues involving tables and queries except the default datasheet font is missing and so far I found no reference to correcting it. Form and report behaviour may not be the same and you may have to adjust some settings. Good luck.
