Hum, that is very strange indeed. Was their any copying of the file(s) to a
cd rom/burner in the transfer? a cd-rom (Read Only Memory) converts files to
a read only format (that is why they are called "rom" which means
ReadOnlyMemory).

If you then copy the files from that CD to your computer..they are still
flagged as read only. You have to right click on the files, and un-select
the "read only" setting.

I suppose it is possible that you are doing this on some server based
system, and perhaps the directory's were you are working you don't have
correct permissions.

However, if the conversion went ok..then I see little, or no reason why the
newer stuff don't work.

Do the files works on your local pc? If they are a linked system, then you
have to use the linked table manger to change the location, or even if just
the name of the files are changed, then linked table manger need to be used,
else you will actually be updating the original back end files!

So, check some of the above things...
