No I couldn't fix it. :( I feel like maybe this was just a joke project since it was posted the same month as April fools, or a practice project that probably won't be updated. Just hoping they answer because a flow chart is what I needed and most other vn engines don't have it.
I dunno I would have to check, but I don't usually have problems because I always install everything I need before using a software since I use many different software. I don't think this SEEVN requires any new driver or framework or anything like that since it's so simple.
Some people is experiencing this issue, sorry for the inconvenience. Please leave information on your computer/device model and OS name+version, that could help us understand the problem and maybe provide a solution.
