Some assistance please… I have 3DS3 installed on a DX2-80. It ran fine for weeks, now when I click the icon I get a "_" prompt in the upper left corner of the screen and then the system hangs. I have tried … Removing the complete 3D3S directory and re-installing the complete program. Same problem. I also have AutoCAD r.12 installed on the same machine. On Friday we attempted to install a softdesk product (CORE) we were unable to use CORE because our version of AC is locked (it is a student version) and while I don't think the problem was caused by CORE I can't be sure. Autoexec and config files have remained unchanges, I even tried to load an older version of WIN and SYS.INI files, same problem. Next I booted directly into DOS and I still can not load 3D3S. Any assistance is greatly appreciated.!! Thx- michaelB
