I can't help you out with sourcing Paradox beyond recommending the usual software suppliers which will come at an obvious cost.
What you can do, if you have anyone who has and knows Access, is import the tables, relationships and data from Paradox into an Access database from which point you can carry on.
It's worth knowing that doing this is no walk in the park and you are better served converting the Paradox database to dBase then heading for Access, since Access sometimes throws a wobbly where Paradox imports are concerned.
If you have Lotus Approach, the same thing goes; convert the Paradox database to dBase then import.
I'm sure someone will be able to help regarding the covermount CD, but if not and you get no further forward, post again and I'll see if there's any direct help I can offer in round tripping the database into a more useful format for you.
