Hey guys, I just installed Proteus Design Suite v8.9 on my computer. But the problem is that the software automatically closes when a simulation is running, or when a schematic is being made. Even during a simple circuit simulation of a Battery, resistor and a LED, the software closes. I've had this problem in Proteus v8.7, v8.8 and now v8.9. I updated to 8.9 hoping the problem would solve but it is still the same. I've lost so many important schematics till now, even when designing it's not just convenient. Anyone facing the same problems? And any ideas how to solve the problems? Appreciate your help.
