Hi, sorry to hear you've been having trouble. It doesn't sound like you're doing anything wrong. I've taken a look through the level transition code again and I'm afraid I haven't been able to replicate your issue, though the problem in your case is most likely the game failing to find the next level or an issue with game data present on the second level. Unfortunately the only advice I can offer at this point is to attempt to re-download the game data, or run the executable as an administrator. I'm sorry that I can't be of more help, but it's been a long time since I've touched this project and my knowledge of troubleshooting beyond Unity is limited.
