can't update/uninstall minimserver 0.72 on raspberry

[prodigy999]

Hi,
I tried your explanation "Updating MinimServer on the Raspberry Pi" but it does not work.

there must be something wrong with the directory.

You write there: 3.Enter the command:
minimserver/bin/update MinimServer-0.8.1-linux-armhf.tar.gz

But i have no such directory in my pi. (minimserver/bin - I have minimserver-0.72/lib)
When i enter this, i get this error - look at my directory:

pi@raspberrypi ~ $ minimserver/bin/update MinimServer-0.8.1-linux-armhf.tar.gz
-bash: minimserver/bin/update: No such file or directory
pi@raspberrypi ~ $ cd minimserver-0.72
pi@raspberrypi ~/minimserver-0.72 $ ls
autostart.sh lib libsys MinimServer-0.8.1-linux-armhf.tar.gz
data libext LICENSE.txt

What should i do?
If you say i should uninstall and install new version, please tell me how to uninstall the 0.72 version.

Thanks in advance!
