BIG PROBLEM please Help with FS9 sceneries

Hi to all,i have a big problem since 4 days ago.

The problem is dme associated to ILS reads 1.7NM at threshold of any world runway with ILS/DME,this means that GS captures according to charts are completely wrong flying in raw data.

Checking the position with complex addon fmc programmed approach,when i´m over the FAF it´s not the correct distance and position from the nav radio tuned on the ILS,it seems like dme is reading from the end of the runway (1,7NM) distance at threshold.

Any help would be appreciated.

Thanks,Alex.
