Hello, we are running simulated distillation methods D2887 and D6352 on a 6890 using Chemstation A10.02 with Envantage simdis software embedded. The computer keeps freezing up one or two runs into the sequence and we can not even open task manager with ctrl-alt-del. We have to do a hard restart. I tried removing the config.reg file and have Chemstation create a new one upon opening. Any ideas of what could be causing this and how to fix it?
