Please try downloading the latest version of Aztec. http://prdownloads.sourceforge.net/aztec/aztec-win32-unstable.rar?download Also, can you say specify when Aztec crashes? before or after the splash screen? Does the main aztec dialog come up at all? > im using an old > 450 MHz AMD K6 > 320MB Ram > 16 MB NVIDIA RIVA TNT I've run Aztec on a similar card before and it worked, Also I run it on a NVIDIA GeForce4 with no problems, do you have the latest drivers for your video card? Thanks! -Jordan Wilberding
