replacement disc arrived with no instructions. Changed, but he does not read discs with games. The system hangs while updating. I contacted Revain and got another one on the way. After some research I found that the circuit board from your original replacement drive needs to be replaced. I found instructions online and exchanged them. It has completed the upgrade and is working well so far. I'm sorry I didn't read it first, but none of the CDs I received came with installation instructions. The sales page also doesn't say they're used discs, which they ship. The whole debacle could have been avoided if they had been clearer in the product description or at least sent instructions with the drive. But at least it works now.
