Cannot see CCMS Monitor Templates - System is not configured

Question

I just finished installing SAP Netweaver Trial, and I have been able to login using the SAP* and DDIC accounts.
I can see the standard tree via the SAP client GUI.
I am trying to take a look at the CCMS Monitor Sets, and I can see the standard collection of "Entire System", "Performance Overview", etc. all fine.
However, when I double-click to load any of the monitors, I see nothing inside.
No sub-trees, nothing.
I enabled "Display error nodes" and see a node that says
"NSP   : System is not configured"
I have tried creating my own user, adding in profiles like SAP_ALL, S_A.System, etc.
I also notice everytime I access the CCMS Monitor Templates, there is an entry in the Syslog:
Severity: Warning
Process Type: D0
Transaction Code: RZ20
Client: 001
User: DDIC
Message ID: BYE
Description:
Database: Invalid parameter ObjTooLar transferred to database interface
Please let me know if I am missing any components, or if there is something I need to do.
Thank you.

Thanks Sunny.
That thread did indeed helped me to resolve the issue.
However, the thread did not really provide clear instructions to complete newbies like me.
For those who also have the same issue, this is what I did:
1. Execute RZ10 (Edit Profiles) via the SAP client GUI
2. Click on the menu Utilities - Import profiles - Of active servers
3. Edit the "Instance Profile" NSP_DVEBMGS00_{Your Computer Name}
Select Extended Maintenance, and select Change
4. Change the following two parameters:
alert/MONI_SEGM_SIZE from 0 to 60000000
rdisp/autoabaptime from 0 to 300
5. In the SAP MMC, right-click on NSP and select Restart
6. After restarting, login and you should be able to see the CCMS Monitor Template nodes
