Changes to structural matrixes?

Hello agin, We are trying to re-create an impact report from roughly Dec of 2008. I have the newest version of IMPLAN, and today I downloaded the 2007 structural matrixes. We are getting the same industries but slightly different numbers for direct/indirect/induced effects. Have the structural matrixes changed in a way that would cause this disparity or could something else be the cause? Thanks

    Structural matrices change every year as they are forced to conform to current year US National Income and Product Accounts. This year (2007) there was also a switch from the 1997 benchmark to the 2002 BEA benchmark. Multipliers will also change because industry characteristics change year-to-year. Eg, output per worker, labor income per worker, and profit to output relationships. There was a change in the 2007 structural matrices in April that would create differences from an earlier run.
