crystal reports on mas90 database

i am having a problem with a crystal report that at one point would run and now is giving me an error
odbc error:canada][pvx odbc driver][fileio] table is not accesible
after you hit ok on that
the second error is
error detected by database dll
what i am trying to run is a crystal report from a mas90 database with an access table. if anyone can shed some light it would be greatly appreciated.
thanks ralph

Have you made any changes to that computer since the last time is ran properly? Try looking up the error number on www.google.com or some other search engine.

i did change machines. and i think it has something to do with the data sources on the new machine but i am not sure what.
but i will give google a try
thanks i appreciate it
