Tomb raider underworld error: wrong disc.. insert original cd or dvd.. go to (securom website).help!!?

Well it happened to me with juiced 2 and I found the problem,if you have ANY image writing program like Magic IO Disc,Deamon Tools,Alcohol etc,they may interfere.If this is not the case sorry dude.But now that I uninstalled Alcohol my juiced 2 works fine
