ms access runtime error 3251 split database

I am sure that there is an easy fix for this as there must be someone out there using the same logic/code. I have search the MS Access Blogs, been in touch with Microsoft (no feedback yet) but have not had any real feedback. It has its own data storage format and also allows you to export other data types and link them with MS Access. Are you running the Access database using a runtime or the full Access client Also, is this app a single Access file containing both the forms and logic as well as data, or is data in a separate file Also, are the files.

Operation is not supported for this type of operation There are number of software available in the market to handle databases but Microsoft Access is one of the mostly used database management system. The code fails on the tblPropertyMaster.Index ='PrimaryIndex' with the error: Where tblPropertyMaster is a (converted) table in the SQL Express Database and the fields, fldTownship_abbr, fldErfNo and fldPortion, are the Primary Key on the table. TblPropertyMaster.Seek '=', fldTownship_Abbr, fldErfNo, fldPortion The tables is visible in the MS Access FE and I can open the tables and see the records. I have successfully converted the MS Access BE Database (Tables) to SQL and linked these tables to my MS Access FE database using an ODBC Connection. I have recently acquired and installed SQL Express on my computer. I have an MS Access 2010 database, split between a Back End Database, holding the Tables and a Front End Database holding the Screens, Queries and Code Modules
