simple question people...i just want to open some schematics in Pspice Student Version 9.1. i have the files, but when i open the schematics, they are blank...somebody said i need to "build" first, but i looked around and can't find anything like that. why can't i just double click on the schematic and it open with the schematic? what procedure do i need to follow before viewing the schematic? thanks...
