This means the database has been damaged.
A "Torn Page" is low-level physical database corruptionIf possible, stop the SQL (ACT7) service and make a copy of the ADF and AFL files before continuing.
The recommended recourse (if the database is attached is to run a Repair Database) in ActDiag - this may or may not resolve the problem.

If there is no backup and you must have the data, you'll need to open an incident with Microsoft - they may or may not be able to go in and manually recover the data and create a new database for you If not, contact Sage Database repair and they should be able to help repair it
