FreeBSD NFA console install/uninstall

Hi guys..
i got some problems with NFA on my system.. freebsd v 6.0 without GUI (something like monitoring server..)
there were no JVM on it, when i try to install NFA.. ./<NFAinstaller>.bin -c
script installs NFA normally (without error).
after that i try to execute run.sh and get

monitor# ./run.sh
run.sh: Missing required file: /usr/local/AdventNet/ME/NetFlow/lib/run.jar

its expectedly because of JVM absence, but now i cant reinstall/deinstall NFA
in <NFA>/_uninst/ i have not file unistaller.bin

monitor# ls
uninstall.dat uninstall.jar

when i try execute /<NFAinstaller>.bin again no mater without or with "-c" key i get something like nothing...

monitor# ./ManageEngine_NetFlowAnalyzer.bin -c
