Navision 4.0(SP3) - facing problem with database restore

We are using Navision 4.0(SP3). I am new to Navision and Database Administartion. I got restored the Navision production database backup (SQL Server 2005) in to our testing environment. Everything works fine from when I setup the application from the restored database but I am not able to execute any of the stored procedures in the SQL Management studio.It gives me the following error

‘Msg 102, Level 15, State 1, Procedure pt_help, Line 1
Incorrect syntax near ‘?’.’
please advise me

Which stored procedurs are you referring to?
