VSM will not start up


I have two problems with VSM simulator.

Firstly, after working normally since it was installed two months ago, the simulator now will not start up. After clicking on the icon it goes through the motions of loading but just as the window is about to open a message box from Windows opens saying the program is not responding and promptly shuts it down.

I have uninstalled and then reinstalled it twice but the program still will not start.

I have installed the simulator in Linux Mint under Wine and this loads and runs fine, but here is my second problem. I cannot get the power and ground terminals to appear on the grid. Instead, I get a rectangular box with the title SUB?

Can anyone help me with either, or better still, both these issues please.
