After Installing the SQL SERVER AGENT for Veritas Backup Exec for V9.0

the server is a windows 2K server SP3, running SQL Server
2K SP2. the problem we have is when we try to view JOBS
under Management. I get the following error.

Error: 3624
Location: rebcase.cpp:1378
Expression: m_offBeginVar < m_SizeRec
SPID: 54
Process ID: 1268

in the Event logs under application we get the following
Errors:
