I used Construct 2 through VirtualBox with Win7 on a MBP Retina.
I also installed the Guest Additions Image.
Everything worked... also my Personal Edition license key.
Made a new game and export it.
But now: if I start Construct 2 and want to start a new project or open an old one, it will shut down.
I also tested older beta versions... the same problem...
I didn't changed the VirtualBox-Settings so far.
Do anyone have an idea to get it working again?
