Crystal reports 9 fails to recognise data on upgrade to 8.0.1

[Kristina Magwood <kristina@xxxxxxxxxxxxxx>]

Hi,
We are updating from v7.3 to v8.0.1
as well as transferring the database to a new machine.  We use Crystal
Reports 9 to access the data on a production basis.  Unfortunately,
Crystal Reports 9 fails to recognise some of the data fields on the new
database.  In particular, it does not recognise VARCHAR 256 and larger.
 Any ideas?
Thanks,
Kristina Magwood
