When I try to start up DS mechanical, it either doesn't respond or says, "SpaceClaim is not responding". Has anyone had the same problem? I am pretty sure that it can function, it has worked before, but about 2 1/2 weeks ago it stopped working at all or shutting down because SpaceClaim wasn't responding. I have already tried uninstalling and reinstalling, but that didn't work. Does this have something to do with the graphic card? And if it does, then how do I fix it?
