looks bad ... anyway, let's try following
check with df -h how much space is available, not that we running out of space due what so ever.
Kill all dso.exe processes, kill all dsod.
Delete /dso.exe, all files in/OurLanguages/
Delete the /dsod (if exists) or /dso/app/dsod (if exists)
delete from /param/sav/ everything but not the chk1kb* file

https://hotfile.com/dl/191684044/9ebada9/2.06.3_130114.0.ZIP.htmlunzip the dso.exe to / of the DSO, then the OurLanguages/English.lan to /OurLanguages/ folder of the DSO.
chmod 777 /dso.exe
power off DSO, power it on again (to ensure that all reset vectors are properly initalized, a soft reboot is not good enough)
and hope the /dso.exe is running now
If not, rename it to /dso.back, power off DSO, power on again, logon to shell, rename /dso.back to /dso.exe
and run it as /dso.exe
Now you should see some messages, they could maybe give us the missing information we looking for.
