Can't get server.sh to start

[SplatZ]

As the title says, I cannot get server.sh to start. I have downloaded all necessary libraries and done the make install thing but every I try to do it it has one error message at the bottom of the terminal:

[SELECT ALL] Code:

cp: cannot create regular file `../../bin_unix/native_server': Text file busy
make: *** [install] Error 1

Also, the weird thing is that sometimes it actually does work. I have no idea what i do differently at those times but it just works.

Edit: Now after restarting my computer, I dont get the error message anymore when make installing. But the server.sh still wont start.

Thanks in advance,
