Hi Stan.

>I got the message 'unknown member oSDTMgr'.

That error means that SDTMgr wasn't instantiated. First, check DBCXREG.DBF: is the SDTMgr record in there? Next, check the mLibPath column in that table: does it point to the correct location of SDT.VCX. Finally, is SDT.VCX included in the EXE?
