Hello guys, my name is zaid and I am third year engineering student. I am now proceeding with my final year project and having a problem with runs PROTEUS software on virtual box on my Mavericks OSX. Each time I try to insert the component in the circuit, it will terminate my virtualbox windows and this a message will appear from some 'meditation guru' sayings that 'A critical error has occurred while running the virtual machine and the machine execution has been stopped'. In the past, Im using Lion OSX which is giving an excellent perfomance and no error at all. Can anyone help me with this problem?

Knowing the VirtualBox version would be useful too. In fact the best thing would be a VM log from a crashed session. For details please read Minimum information needed for assistance.
