This translates to /home/user/MyDocs/Date/preenv game/ inside rootfs which starts as / . Better don't use spaces " " in directory names, makes for difficult typying in terminal hiding the space to the shell. Common practice in linux is to use underscore "_" instead.
The mount options for MyDocs partition must changed to executable. Search for it,please.
My advice would still be: Educate yourself about repartitioning you internal flash http://wiki.maemo.org/Repartitioning_the_flash to have proper space available for installed applications in optfs, aka /dev/mmcblk0p2.
