The problem is which burner you have...since stronghold is safedisc 2 protected, you must habe a burner which is capable to perfectly copy it (Philips chipset based burner)...check the Clone CD supported wrtiters page ####://www.elby.org/CloneCD/english/index.htm...another solution is to install the fixed.exe provided at GCW...to open the .ace file, you need a program like WinAce, but I'd recommend Power Archiver ( ####://www.powerarchiver.com ) ....it can unzip all kind of compressed files, and most important, it's freeware.

hope that this can help
