Hello, thank you for your support.
I'm sorry to hear you're having a problem with Female Forge. I've sent you a technical support email so we can try to find a solution to this problem.
[Edit:] This problem has been resolved privately. It was due to a screen resolution not supported by Female Forge; you simply needed to uncheck "Fullscreen" on the resolution selection screen and choose the lower resolution that most closely matches your native resolution.
