LG-GSA2166 & LS problems

Hi guys
I finaly got this drive and must admit that works perfect…almost,with excellent quality.The only problem i have is with the lightscribe function.
When i install the nero vision xpress which comes with the drive,the LS works perfectly.But if i install the last version of nero burning rom premium i have no LS support.
Why?LS is installed and if i open the label design of nero,under preferences exists the LS label but CAN’T find my drive.
What can i do?
I don’t like nero xpress and need nero 7.
