I have very little experience with using this but I have found that if you have SAS Access for PC Products licensed, just as you can issue a libname statement pointing to an Excel workbook, you can also issue one for an Access database. Try doing this and then look at your SAS explorer window where you will see an icon for the Access file and will then be able to look at the Access tables as if they were SAS data sets.

Export to tab or csv and import into SAS. The export procedure from Access is relatively painless. If you've already done that and are still facing problems you should provide more info on variable formats and code used as what you're doing should by no means represent a problem for SAS.
