[solved] couldn't get NX work after switching to 64 bit system

Question

I switched the system to 64 bit with my "home" folder untouched. Then I couldn't get NX work. Here is the detailed output:

You might also want to try: ssh -X myserver; /opt/NX/bin/nxnode --agent to test the basic functionality. Session log follows:
Can't open /opt/NX/var/db/running/sessionId{593D8F5A1C9C4FC7C01CA605A678F07D}: No such file or directory.
mv: cannot stat `/opt/NX/var/db/running/sessionId{593D8F5A1C9C4FC7C01CA605A678F07D}': No such file or directory
NX> 1006 Session status: closed
NX> 280 Exiting on signal: 15
I guess there are two problems with it:
1. It couldn't resume. (in fact I want to start a new session. I don't know where are the old session information: I already removed all related file in the home folder.)
2. the error with "nxagent". It says it couldn't load libXcomp.so.3. I don't know how to install it.
Any help will be appreciated.. Thanks!

Thanks for your reply! I do have Xorg installed. And The X works fine on the local computer (not remote login).
Here is the result from "locate libXcomp":
