Both Projections are not handled correctly by CompeGPS (6.5.1)

Bugfix:
Edit the following files in the projections-Subfolder of Compegps:

CompeTMProy_GK-System 9.dat: change FE=4500000 to FE=3500000
CompeTMProy_GK-System 6.dat: change FE=4500000 to FE=2500000

The files have obviously just been copied from the GK-System 12 which is correct.

These Projections are used by some maps in Germany - eg. WMS-Services.

The file for the 9 Projection has already been sent to the support.

Cheers
