galleryserverpro.config must have a decimal point instead of a comma in the numbers. Open it in a text editor (it is in gs\config\) and replace 1,33 with 1.33. You may also have to fix the value for mediaObjectTransitionDuration - change it from 0,2 to 0.2.
One you repair the config file, the fix described in the other thread should prevent the numbers from being written with commas.
