Nero Software Suite 7 NMIndexStoreSvr.exe

Hey, I just tried my new burner(LG GSA-H42N) and new media (TY DVD-R 8x's) to burn some data DVD's to back up my stuff before i reformat my computer, and its the first disk i tried burning with this combo, so i want to know where exactly my mistake came from.
I just installed Nero 7, and i keep getting this NMIndexStoreSvr.exe since that happened, so i'm kind of wondering if you guys could tell me what my problem is.
Please refer to the image below.

Error:
Burn process failed at 16x (2,400 kb/s)
