LG Burner Help

I have an LG BH08 that I have had since January. I have burned a lot of blurays with this burner no prob. But I went and cleaned the lens with a DVD lens cleaner and the unit will not read original blurays. If I put one in and go to my computer it just shows the drive. and when the disc is in there it kinda makes a clicking noise but does not read. Now if I put in a backup of an original it will show up. Just wont read originals. I have win7 on a AMD 945 Phenom II with 4 gigs of ddr3 1600. Never had any pronblems until I used the lens cleaner. Any sugestions? I already contatced LG and they are supposed to be sending out another but I have some blurays I need to back up right now. Also I just tried and burned a 4.7 dvd with data to see if that worked and it burned fine.
