I have already installed Infor server 8.1 and SSA ERP 6.1 without any error. But i receive the SLM warning message in the event log. And i can't install sample data base due to error "no package combinations found for ERP_demo_data_demostrationdata"

I have not registered Infor LN yet.

Is it ok if i register application at this time? Or do as following step:
+ Reinstall server
+ Reinstall SLM
+ Register to activating system
+ Reinstall Infor Server 8.1
+ Reinstall SSA ERP 6.1

About the question for SLM installation and configuration:
+ Please help me to find and config the license file. I don't understand some field for configuration:
1. What is the product ID of LN ERP 6.1?
2. We have purchased LN 6.1 name user. So what is the meaning of ligh user and heavy user.

This is the first time i install LN ERP. So if i get error after submit SLM file and activation code. Can i clear server and reinstall?

Please help me asap

You do not have to re-install the whole Application to register your license.
