Cubase crashes with R6025 - pure virtual function call. My soundcard is then disabled until I reboot. Wavelab just crashes without any error. I have stopped and restarted .Net framework, reinstalled Visual C++ and Cubase all to no avail. I Have requested Tech support from Steinberg who have yet to respond. Is this likely to be hardware or software related? I have seen lots of this error on the forums with no definitive answer. The internet gives a range of answers mostly to do with reinstalling - which I have done, and using registry cleaners - which I am wary of doing. My DAW computer has only been in operation for a few months and isn’t as a rule connected to the internet.
