DMT Error - 9.05702A

I am getting a strange error when I try to import my Order Header.

This is the error:

013-07-01T15:29:47 18739V6 Table: Msg: Sql is not valid.
2013-07-01T15:29:48 64288V6 Table: Msg: Sql is not valid.

2013-07-01T15:29:54 16523V6 Table: Msg: Sql is not valid.

could my DB be corrupt?? I can log on fine and access the data.

Thanks Kim
