LOL Radek! That one is amazing...
I was thinking later on last night that this might be a legit complaint...
I mean, you need to have CD2 in the correct drive in order to play. What if the person were trying to play without it and did a bad translation of the error message? Or (*sinister music*) what if their CD2 were not a "factory-fresh" CD2, and was missing a little something? That might have brough them into the same spot...
