I've uploaded a fixed template_6 folder here:

http://server.conitec.net/down/template_6.zip

Please unzip it in your Gamestudio folder. It replaces some files in your template_6 folder.

The old version had two mistakes: The script templates used the A4 keyword EXIT instead of the A6 sys_exit(), and the file default.fx was erroneously included where it shouldn't. I could not see any problem with the startup screen template, though.
