[Dxbase] problem initializing after adi import

Mon Apr 4 16:47:15 EDT 2011

Hi,
I have done this dozens of times but this time:
loaded adi from contest log using non dxbimport
all the calls loaded without error
started dxbase 2007
initialized tables and error 1601 come up 
error 1601 there is no message for this error.
so I shut dxbase down and tried again.
this time upon initialization, program shuts down immediately
so I went back to saved mdb database
all calls seem correct in log upon start
I initialize tables and programs shuts down immediately
what should I do next?
