Database conversion error

When trying to convert database from 2007 to 2014, I receive the following error:

Class: tBDEFieldExceptionC
Code: 11
Area: Table
Attempted to read damaged data.

Please close and then restart Timeslips. If this error happens repeatedly, please contact the Technical Support group.
Exception tBDEFieldExceptionC in module Timeslip.exe at 00B19126.
Table: Timekeeper Security
Record: 49
Field: Personal Settings
BDE Code: 0

I ran Data Verification to correct integrity errors, but same error code came up. Any suggestions?
